And who puts the GOP folks where they are?
Ultra-conservative Tea Party types. And people selfish enough to vote for crazy candidates because they promised tax cuts, even if they personally disagree with the bigotry. Trust me, there's a lot of liberals, moderates, women, and people of color who are not happy
with the current crop of leadership. And the GOP's getting so extreme and bigoted that the whole "tax cut" routine isn't working anymore.
I will say that there are problems with race in the US. We have come very far, when members of certain races couldn't even vote or get fair trials decades ago, but there are still some racist expressions and stereotypes in the media which are either tolerated or go unchallenged. Some of them are dead and buried, like blackface minstrel shows, but others, like the image of Latinos being lusty and sexually uninhibited, are still present.
