I don't consider myself a moderate (with the exception of some environmental issues and some social issues fiscal and labor issues where I take a more libertarian communitarian approach), but it drives me nuts when the party acts like a bunch of hacks and is unwilling to compromise.
^^^ Basically this.
Oddly even more than being unwilling to compromise, the Republicans' problem is also they we are marketing ourselves as unwilling to compromise. Sort of like how some of the left on here like nothing more to advertise how extreme they are, the GOP seems to be trying to do this in real life. A lot of times that's a bigger electoral problem than whether or not we're willing to compromise in the first place.
They had to to win the Tea Party vote (and to avoid getting primaried)... now they're stuck.
