There are plenty of conservatives that are assholes, just as there are on the other side of the aisle. The majority of both sides are decent people that vote along party lines in reality, even if they're not particularly thrilled with their candidate. The real question is independents, how they're convinced to vote for either of these crummy candidates I can't say.
Looking at a majority of people like they're assholes, no matter which side you support, is a horrible way to go through life and not an accurate representation. Assholes are everywhere and probably account for just...10-15% of the country lol.
