The problem with trying to keep sane Republicans in office is that they so often talk a good game but then in their actions go along with the most insane behaviors. Not a single Republican voted for Obamacare, even though just a few years prior it had been a Republican suggestion. All these sane Republicans voted to shut down the federal government to assuage Ted Cruz's ego. All these sane Republicans repeatedly attempted to crash the world economy by defaulting on the debt ceiling. All these sane Republicans are currently blockading the most worthy Supreme Court nominee in decades, solely to give a middle finger to Obama. These are not matters of policy. This is reckless partisan hackery at the expense of the country, point blank. "Boooo democrats, Jeff Flake and Joe Heck are such nice guys, but you ruin everything by trying to defeat them." They may be nice guys and have some decent ideas in private but once they get in the Senate they pull sh*t like this:
and at that point they're no better than Ted Cruz.
Now that doesn't mean there aren't a bunch of reckless political hacks who put their political hackery ahead of the country on the Democratic side as well. But the way the Democrats practice that political hackery is far less dangerous and destructive. The worst the Democrats ever did was when they tried to defund the Iraq War as a middle finger to Bush, but that never went anywhere, and I'm pretty confident that if it had had any chance of actually becoming anything more than just political theatre, the party would have shut it down, because
defunding an ongoing war for political purposes is an insane, stupid thing to do. The GOP seems to have no such qualms.
Show me a Republican with the integrity to actually do what they know is right and not +1 these stupid, destructive escapades that the Congressional Republican majority is obsessed with, and I might just vote for him.
