McCain going into the oval office makes him ripe for being slaughtered by the media and Democrats ala watergate style. Like Nixon, he’ll have very little support from the base, because he burned too many bridges in the party. Who will care to support him if a scandal hits a McCain Administration?
Sorry for the digression, but I agree with your assessment. McCain is a useful idiot for the Dems right now, but as President, he's just another R and they'll do everything they can to destroy him. The Pubbies pee themselves if a congressman gets caught taking three ketchups when he only needs two anyway. What are they going to when it's McCain and they don't even like him?
