I've only been on these boards a bit over a week and this question or variations of it have popped up several times.
Let me ask a question in turn.
If there were two candidates for office. One has all the good stuff you want in a candidate except for being pro-gun control and the other everything you despised in a candidate except for being anti-gun control; which would you vote for?
Stalin, Hitler, and Satan and no gun control
Or
Washington, Lincoln, and Jesus and gun control
