The US is not a parliamentary system. Our two party system is not conducive to incremental change. Unless the majority of Republicans revolt, we are stuck plodding along toward Gomorrah. Given the numbers of those people even on FR who will vote straight R, the likelihood of change is next to nothing.
Two years until the end game. Keep your eye on the ball, Charlie. Party uber alles!
It's not a two party system, that's the lie that makes it unconductive to change.
