People when they talk about the Republicans being divided because Tea Partyists and others want a "true conservative" don't notice that the Democrats have been hungry for a "true liberal" for awhile as well.
They are tired of "pragmatists" who can win elections but end up changing little when in office.
President Obama was their great hope, but his horrendously incompetent performance has left them with sour tastes in their mouths.
But Obama's not incompetent. Don't you remember what situation the economy was in when bush left office? Actually the picture looked pretty bad for the whole world thanks to your clown act of bush/cheney. Same thing happened during the republican great depression before FDR fixed what your party screwed up. And then of course, 9-11 with no protection from our military. Then the Iraq fiasco and no WMD's.
This is what will be in the history books. Leave running the country up to the democrats who are the adults in the room.
