Many newspaper and television reports have recently described Bernie Sanders’ quest for the Democratic nominee as an uphill battle. It seems that Hillary Clinton has an insurmountable lead in the votes and delegates to win the nomination. The phrase uphill battle is an interesting metaphor in this usage for several reasons. At first glance, it seems that it is a mixed metaphor, mixing journeys and military concepts. Technically, there is such a thing as an uphill battle, one in which an army must fight an enemy while moving up a hill or mountain. However, it is more likely that we think of this as a sort of compound metaphor combining the physical struggle of walking uphill with the danger of fighting a battle in a war. This compound metaphor makes us think of obstacles to journeys and military campaigns. I have described some of these metaphors in past blogs, but it is interesting to see how they are combined into one conceptual metaphor. Here is a review of metaphors of obstacles on a journey and military battles.
Obstacles on a Journey
obstacles
On some journeys, there may be obstacles or things that prevent continuous progress, such as animals crossing the road, snow or rocks falling on the road, or bad weather conditions. Metaphorically, there may also be obstacles to continuous progress for the success of a program or any process.
Example: Barack Obama had to overcome many obstacles in his path to becoming the first African-American president including growing up poor, not having a father, and succeeding in an environment dominated by white politicians.
block
A block is a large log, brick or any compacted mass. A block can literally prevent the passage along a journey or prevent progress in an endeavor.
Example: Unfortunately, when a Republican president is in office, the Democrats often block the passage of the Republican bills, while Republicans often block the passage of Democratic bills when a Democrat is in office.
Similar to the idea of obstacles, roadblocks can literally block the continuous progress on a journey or metaphorically block the progress of a program.
Example: In the first two years of Barack Obama’s presidency, the Republicans seemed determined to prevent any success of the Democrats so they put up many roadblocks in Congress.
stumble, stumbling block
A person can also trip or stumble on a branch or a brick in the path along a journey. Metaphorically, one can also stumble or have to overcome a stumbling block in the middle of a process.
Example: President Obama encountered many stumbling blocks from the Republicans and insurance companies when trying to pass health care reform in 2010.
When one cannot continue on a journey because of a road being completely blocked by a natural disaster, we say that we have met an impasse, literally something that blocks the passage of a person.
Example: When Bill Clinton tried to pass health care reform in 1994, he ran into an impasse with insurance companies and other politicians and failed to pass any new legislation.
break down barriers
Another word for a roadblock is a barrier. To continue on a journey, one may have to break down the barriers. Metaphorically, one may also need to break down barriers to make progress in a process.
Example: Barack Obama had to break down many race barriers on his way to become the first African-American president of the United States.
bridge, bridge builder, bridge the divide, bridge the gulf
If one needs to cross a river or a valley during a journey, one may need to build a bridge to be able to continue the journey. Literally, this is called bridging the divide or bridging the gulf.
Metaphorically, when two people or groups cannot agree on something, someone may offer a compromise to solve the problem. This may also be called bridging the divide. The person who does this may be called a bridge or a bridge builder.
Example: Sometimes a U.S. president may need to bridge the divide between the Republican and Democratic members of Congress.
clear the way
Sometimes, if a road is blocked, one must clear the branches, wood or rocks away before one can continue. This process is referred to as clearing the way. In common terms, we can also clear the way for a process to continue after it had been delayed.
Example: In the 1960s, the work of Martin Luther King, Jr. cleared the way for the civil rights laws that were passed later that decade.
Paved roads in cities often develop holes after many years of traffic and bad weather. Some of these holes are so big people say that they are as big as a cooking pot. City crews must fill the so-called potholes so that people can continue to drive on these roads without hurting their vehicles. Metaphorically, any process that has many difficulties or delays may be described as having many potholes to fill especially when used with another road metaphor.
Example: After the economic crisis of 2008, President Obama had many potholes to fill on the road to recovery considering problems with the banks, corporations and high unemployment.
sidestep
Some obstacles in the road are very small and can simply be avoided by walking around them. We can call this action sidestepping the obstacle. In common terms, we also say that one can sidestep a problem or an issue by not dealing with it directly.
Example: Many candidates running for office sidestep controversial issues such as abortion and gay marriage.
recourse
A course is a route that one follows on a journey. The route to return to the starting point of a journey may be called a recourse. Metaphorically, a recourse is something that one must consider when the first plan does not work.
Example: After years of fighting a war in Afghanistan, the U.S. government had little recourse when their military could not defeat the Taliban there.
long, uphill task/struggle/battle
Walking on a level road is easy; walking uphill is more difficult. Metaphorically, a difficult task may be called an uphill struggle or an uphill battle.
Example: When John McCain returned to the United States after being a prisoner of war in Vietnam for several years, he had an uphill struggle to regain his health and his military career.
look beyond/move beyond
On a long journey with many hills, one must try to look over or look beyond the hills to see the rest of the road. In common terms, one must look or move beyond an obstacle to solve a problem.
Example: After many lost seats in the 2014 midterm elections, Democrats had to look beyond their losses and plan for the 2016 presidential election.
Battles

primary battles
Battles are the names of the primary engagements between armies in a war. Metaphorically, battles can also be fought verbally between people or groups. The notion of battle is commonly used in politics.
Example: In every presidential primary, there are many battles among the candidates to gain the nomination of the party.
battle cry
At the start of every battle, there is a call or cry from the commanding officer to alert the troops to begin fighting. The phrase battle cry can also be used to indicate the beginning of a political process.
Example: In 2011, the Occupy Wall Street protestors used the slogan “We are the 99%! as their battle cry to gain support against the richest 1% of the nation controlling the government.
battleground states
The land where battles are fought are called battlegrounds. In politics, states in which voters may vote for either Democrats or Republicans are called battleground states when candidates fight for the votes for their party.
Example: Ohio and Florida are often considered battleground states in presidential elections.

battle lines are drawn
The exact line separating the land controlled by two fighting armies is called the battle line. Metaphorically, a battle line is the ideological separation between two people or groups. In a public political argument, we may say that battle lines are drawn based on a certain view of a controversial topic.
Example: In the 2016 election, Democrats drew many battles lines with Republicans over the tax breaks given to millionaires and billionaires.
combat
Combat is another word for battles fought between armies in a war. Metaphorically, any verbal argument can be described as combat as well. As a verb the word combat can be used to describe efforts to fight against something.
Example: George W. Bush worked hard to combat the spread of AIDS in Africa during his presidency.

firefight
A firefight is an intense battle between two armies in which a great deal of gunfire is exchanged. In politics, a heated argument may also be called a firefight.
Example: Sometimes a peaceful presidential debate turns into a firefight among the top candidates.
clash
The word clash is an onomatopoetic word meaning that it represents the sound made by two metallic objects hitting together. A physical confrontation between people or battle between armies may be called a clash. However, metaphorically, a disagreement in words or ideas between two people or groups may also be called a clash. Often we speak of a clash of personalities between two people.
Example: During the 2016 Democratic presidential primary, Hillary Clinton and Bernie Sanders clashed over positions on the economy.
*******
As I have mentioned many times, political campaigns are thought of as military operations, judging by the amount of war metaphors we used to describe them. The process of winning a nomination or becoming elected is also thought of as a long journey filled with obstacles. When a candidate struggles to win a nomination for his or her party, it is logical that the process be called an uphill battle.
