That's the problem. The GOP wins a mid term election and then think their inter party issues are gone. They aren't. The GOP can't govern. They prove this time and time again. It's one thing to spout vitriolic nonsense to your base during an election and swear on the bible that you'll defund this, repeal that, "take back the country" (from what no one knows), etc. It is a completely different thing to actually do this. Even with a majority in both houses, the GOP has proved incapable. There's no leadership, no common goals, no willingness to compromise for the good of the nation, no sacrifice, etc. The GOP should split. Let the hardliners go their own way and the moderates and intellectuals go another.
If the Pauls had any guts they would have started their own party years ago, but they don't so they didn't.
