I do think that the Democrats should give up on gun control. I generally agree with their stance on it, but it's just not that important. I see so many reasonable people who agree with Democrats on nearly everything, but love their guns. Some of them hold their noses and vote D. Many of them refuse to, because they really love their guns, even though they lean that way on almost everything else.
I completely disagree on abortion, though. That's a serious health issue that will result in a lot of unnecessary innocent deaths if the "pro-life" side gets their way. That is an issue worth fighting for.
