The good news! for John McCain is that ex-Rep. and current right-wing talk show host J.D. Hayworth hasn't made any moves toward running in a GOP primary. Hayworth has been rumored to be interested, but that may simply a way for Hayworth to yank McCain's chain. Former Minutemen leader Chris Simcox is definitely running, but this poll indicates he doesn't pose much of a threat. PPP -- the only other pollster to look at the GOP primary field so far -- found McCain leading Simcox by a closer 61-17 in September, so it looks like there's a hardcore base of anti-McCain votes who prefer Hayworth but would still go for the even more extreme Simcox. (PPP didn't test Hayworth.)
The bad news! for McCain is that Hayworth may see these numbers, see the general anti-incumbent, anti-establishment climate on the right, see the organizational pieces falling into place (Club for Growth, Freedom Works, etc.), see little Democratic general election opposition (up-and-coming Tucson city councilor Rodney Glassman is the only Dem in the race), see lingering conservative resentment toward McCain for his occasional bipartisan moments and his incompetent presidential campaign, and think well, why the hell not?
