Arizona Republican Senate candidate J.D. Hayworth is trumpeting support from backers of 2008 GOP presidential candidate Mitt Romney.

That would not be considered out of the ordinary, except for the fact that Romney has endorsed the man Hayworth is challenging; Sen. John McCain (R-Ariz.)

Hayworth, a former congressman and talk radio host, took to Twitter Wednesday to show that Romney supporters have created a Facebook group titled "Mitt Romney Supporters for JD Hayworth."

Observers predicted that Romney's endorsement would allow McCain, the GOP presidential nominee in 2008, to collect conservative support that he needs since Hayworth is challenging him on the right.

As with any endorsement, it's unclear to which candidate Romney supporters will flock. So far, the Facebook group only has 66 members.
