If McCain is the Republican nominee, and Obama is the Rat nominee, we will lose. It will be child's play for the leftwing media to contrast "the jobs aren't coming back, there will be more wars," McCain with Obama's wispy message of hope.
I'm starting to think that the best of all possible worlds (if McCain wins the nomination) might be for him to be branded as a loser, get him out of the way, and let the vastly inexperienced Obama fumble his way through two years while we rebuild a Republican Congress. Yes, we might get a city or two nuked by the islammofascists, but look how many people in New York have already forgotten the lesson of 9/11. We might just need a fresh reminder of what it means to deal with enemies the old fashioned (WWII) way.
Two years of President Obama will make George W. Bush into a national hero figure by comparison. And we wouldn't have the pure evil of Hillary to deal with anymore.
If it is Obama versus McCain, it will be Clinton versus Dole all over again.
