The Tea Party may be the key.
If the Republican candidate needs the Tea Party imprimatur to be nominated that may force that person so far right it would turn the stomachs of many people.
Hopefully a Bush by the same name is still a Bush. Just because he's not as bad as his brother doesn't mean he's good.
The Supreme Court's decision that unlimited money can be raised means that the Republicans can promise to sell the country on an unprecedented scale and money buys elections. I don't think there is any real question that the next president will be Republican. They got Bush into office a couple of times and Sarah Palin has a strong following. Imagine that - Sarah Palin.
