McCain Supporter "Circulating" Mitt Romney Donation

The Politico is reporting that a "well-connected" McCain supporter is "circulating" the fact that Mitt Romney gave $250 in 1992 to the campaign of former New Hampshire Representative Dick Swett (D) has made a point of noting that Swett is a Mormon. Is this an attempt to bolster the Damon Linker note of caution that Mormon politicians hold their faith above their allegiance to their country?

In response, a Romney spokesman said: "A $250 contribution made almost 15 years ago is, obviously, greatly overshadowed by strong conservative governing and a proud, Republican record of balanced budgets and pro-family advocacy."
