RNC ploy to dump Bush and replace him with McCain?

[malatesta1137]

Democrats.com:

Some of us suspect that many in the GOP are hoping to dump Bush as the party's candidate and put in John McCain, the man most likely to make the best showing. First, they trumped up a pretext for disseminating plenty of McCain info in the news by floating the rumor that McCain might be Kerry's VP choice. Now, there is a high-profile "conflict" between Dennis Hastert, who represents the hardcore rightwing Bush loyalists (a rapidly dwindling group), and McCain the moderate who represents the "better way." The fact that Hastert blustered that McCain wasn't a "real Republican" strongly suggests he suspects that McCain represents a formidable rival to Bush within the GOP itself.

Any thoughts?
