More and more Republicans today are wishing the same policy applied to political candidates. Both publicly and privately they admit they'd like to trade Mitt Romney in for somebody who could win...

After a readily forgettable convention, he's fallen behind in the national polls. He lags in most of the swing states. His campaign has given up on Pennsylvania and Michigan. Without a clear campaign strategy, he just seems to lurch from one faux pas to the next. And it's driving conservatives, so desperate to get rid of Obama, crazy.

"If you can't beat Barack Obama with this record, then shut down the party," conservative talk show host Laura Ingraham told Republicans. "Shut it down. Start new, with new people." Reacting to Romney's failure to capitalize on those disappointing job numbers, columnist George Will piled on: "If the Republican Party cannot win in this environment, it has to get out of politics and find another business." Even Rush Limbaugh had to admit, "Romney is not the perfect candidate." But that's OK, Rush insisted, because Republicans are voting against Obama, and not for Romney. "He may as well be Elmer Fudd as far as we're concerned." It's not a good sign when the leader of the Republican Party compares his party's presidential candidate to Elmer Fudd.

Romney's not even talking about jobs, anymore. Ever since he named extreme social conservative Paul Ryan as his running mate, he and Ryan, instead, have been talking about everything but jobs: abortion, rape, contraception, Social Security, Medicare, and Medicaid. Which, again, drives conservative pundits nuts. They know Republicans can't win on Medicare, Medicaid, and Social Security.

To make matters worse, Romney makes an even bigger fool of himself whenever he ventures into foreign policy. Any suspicion that Romney might be ready to assume the awesome responsibility of leader of the free world vanished this week as soon as he opened his mouth about Libya.
