Each election cycle, there is one factor that seems to drive support and participation all the way to victory: passion. When voters are enthusiastic, they will not only give pollsters their candidate preference but are very likely to pursue it at the polls on Election Day. This intensity can be just as powerful when voters are for a candidate as when they are against one. It is part of the reason that President Trump won in 2016.

Despite personal opinions about the commander in chief, it is clear that he elicits excitement and deep loyalty from his base. While President Barack Obama also garnered a massive, unquestioning following, not all candidates are able to do the same. Though Hillary Clinton enjoyed plenty of support from Democrats in 2016, especially women, her opponent seemed to enjoy a more intense backing. Clinton captured votes from those who believed she was qualified and would do well. Trump captured support from those who fervently believed that he absolutely had to win.
