That's from the latest PPP poll, which also asked people if they had a higher opinion of Trump or hemorrhoids/cockroaches/Nickelback/used car salesmen/traffic jams/hipsters/DMV/root canals/jury duty/lice.
I guess there are people in the mood for campaign-related humor, but PPP is supposed to be a serious operation, and you'd think they wouldn't want to associate their brand with that kind of junk. Maybe the idea is to make light of the part of the poll that is actual news:
Clinton leads Trump 78-9 among Democrats in the full field at this point, while Trump leads Clinton 78-7 among Republicans. Although much has been made of disunity in the GOP, it is actually just as unified behind Trump as the Democrats are behind Clinton. 72% of Republicans now say they're comfortable with Trump as their nominee to only 21% who they aren't. Those numbers are little different from the ones among Democrats that find 75% of them would be comfortable with Clinton as their nominee to 21% who say they would not be....I had to go to the full results page to find out how Hillary does against Trump. It's 42 to 38% (with Jill Stein and Gary Johnson included) and 47 to 41% (with just Hillary and Trump).
