Romney will mainly slow down the disease a bit, which will give us time to build a new party system. We could not possibly do it with Obama in office. He would declare us illegal under his new Executive Order.
Romney has a good chance of winning, so that is our only hope left to stop this. This will be similar to using a pest species in our garden, to kill destructive vermin, which in turn comes a time to get rid of the original pest species. (Romney) And above all else, I don't count out the possibility of a Brokered Convention or immediate 3rd party effort.
I agree with you that Romney will betray conservatives. He’s going to pull a McCain (a la his Senate reelection), and then everyone will be SO SURPRISED, like it’s never been done before.
