There is a significant amount of dislike for the Republican Party itself coming from these GOP primary voters as well: more than a third of Republican voters – no matter whether or not they support Trump — have an unfavorable opinion of the Republican Party.
These negative assessments are very different from how Democratic primary voters feel about their party and their party’s leaders. 81% of Democratic voters have a favorable opinion of the Democratic Party (and 71% of those supporting Vermont Senator Bernie Sanders, who did not declare himself a Democrat until he ran for president, agree). House Minority Leader Nancy Pelosi and Senate Minority Leader Harry Reid are viewed favorably, though many primary voters have no opinion. And as for current and former Presidents, Democratic voters like them both – a lot.
