Actually, a lot of the 'Rats would be better off with McCain than with Obama. McCain will give most of the 'Rat Senators what they want (the hardcore leftists wouldn't get what they want, but even under an Obama presidency they'd probably be held somewhat in check by the moderates).
McCain would probably be less destructive to the country than Obama, but more beneficial to most of the 'Rats who would prefer not to have the country collapse too completely before they've managed to get their 'piece of the action'.
