Republican and Democrat views on their candidates

In 2007, Democrats were excited about their primaries. With Barrack Obama, Hillary Clinton, and other candidates, 65% of Democrats had an excellent or good impression of the candidates that were running. Republicans were less enthusiastic, with only 50% having a good or excellent impression of their field. In 2011 Republicans were at 44%. Democrats had no polling because Obama was clearly going to win. In 2015, this year, Republicans are at 57%--higher than all of the other years. Democrats are at 54%. Neither side seems to be as rilled up as the Democrats in 2007, but Republicans seem to be more excited than the democrats. But the polling is within the margin of error.

This is based on a Pew Research poll.
