The way I see it, the country is going to be destroyed either way. A whole bunch of us joined the GOP to take the party back to it's Taft-Goldwater roots. If the nation is destroyed under a Democratic regime, then the Dems will get the blame. If the nation is destroyed under a Republican regime, then the Reps will get the blame. It is better, then, for those of us who have committed to the 4, 8, and 12 year GOP plan, that the nation collapses under Obama than under McCain.
Now, that said, an Obama Presidency would mean some very scary things for gun owners and the US Supreme Court. Nevertheless, in 4-8 years when it comes time to rebuild the Republic from the rubble of collapse, it will go far far better for the folken of the Ron Paul platform should the Republican brand not be saddled with the collapse of American civilization.
