John McCain is receiving on-air endorsements from Florida Gov. Charlie Crist (R) and country music singer Hank Williams Jr. in two radio ads the campaign recently released with the Republican National Committee.

Both men take jabs at Barack Obama for controversial comments he's made -- recent and not-so-recent. In "Spread The Wealth" (subscription), Crist references what Obama said on Oct. 12 to Joe "the Plumber" Wurzelbacher of Ohio explaining why he wanted to raise taxes for Americans earning higher incomes. "John McCain knows that people don't want to 'spread the wealth,'" Crist tells his Florida constituents. "He knows that Congress should let you keep more of your money, and not take it away."

Another infamous comment -- uttered by the Democrat at a private fundraiser in April -- where he said some rural Pennsylvania voters were "bitter" and "cling to guns or religion," is the focus of "Hank Williams Jr." (subscription). Williams tells listeners the comment proves that Obama "just doesn't understand small-town America." Aiming to pit rural voters against the Democrat, he continues: "We love our God. And we love our guns, especially handed down from our grandfathers. And we resent it when liberals like Obama question our way of life." He concludes by urging voters, "Don't be bitter. Vote McCain."

Williams has been an avid McCain supporter for a while now, even devoting a song to the GOP ticket.

Since both 60-second spots are co-sponsored by the RNC, Crist and Williams occupy just half of the running time in each. By law, these ads must devote at least half of their time to a more general focus. The latter part of both spots give way to attacking "congressional liberals" for their tax-and-spend policies and being "out of touch" with America.

With McCain short on cash, pairing up with the RNC on the radio is a cost-effective measure, but ending on such a generalized tone in each spot may tend to blunt the more pointed attacks made at the beginning. McCain and the RNC did recently discontinue their joint TV ads.
