The John McCain mutiny

Am I the only one who thinks it's odd that a bloc of right-wing talk show hosts are united against John McCain? Rush Limbaugh, Sean Hannity, Laura Ingraham and Hugh Hewitt have all come out for Romney.
Said Ingraham in the Washington Post, "There is no way in hell I could pull the lever for John McCain."
Not only that, Rush Limbaugh, never one for being in the background, says he'd support the Democrats in the general election if it keeps McCain from being elected.
"If I believe the country will suffer with either Hillary, Obama or McCain, I would just as soon the Democrats take the hit . . . rather than a Republican causing the debacle," he said. "And I would prefer not to have conservative Republicans in the Congress paralyzed by having to support, out of party loyalty, a Republican president who is not conservative."
Does anybody really believe this hogwash? Why do we smell a little Republican mischief here? What drugs are these guys on? After all, all of these talk show hosts march lockstep to GOP marching orders. Limbaugh support a Democrat? He'd rather have a boil removed from his backside.
McCain adviser Mark McKinnon went along with the game. "Our question is, 'Isn't it better to get behind a Republican you may disagree with from time to time than work for an outcome that puts a Democrat in the White House with whom you will disagree all of the time?' . ."
As the Post suggests, this is most likely an attention-getting maneuver by Limbaugh, who revels in being in the spotlight.
Wouldn't it be funny, though, if this strategy backfires in his face?
