The buzz before last night's GOP presidential debate was that former Senator Rick Santorum could solidify his front runner status with a win and former Massachusetts Governor Mitt Romney could be in big trouble if he lost. Well, Mr. Santorum didn't win and Mr. Romney didn't lose and that's about all the news that was made at debate #20.

Forget those two tedious hours, a new 30 second ad from the Santorum campaign could have a much bigger effect on the race in general and Tuesday's Michigan primary in particular.

The ad is a stark reminder of some decidedly un-conservative positions taken by Governor Romney on such issues as gun rights, abortion, taxes and government provided health care.

Romney spokesman Ryan Williams responded by calling the ad a "dishonest attack" and "a desperate attempt to distract from [Santorum's] long career in Washington and his decision to repeatedly increase the debt ceiling and his own pay."

But it's difficult to believe the claims of dishonesty when the ad contains direct quotes both from Governor Romney and such reputable media outlets as the Boston Globe and the Philadelphia Inquirer.

The latest poll shows Mr. Santorum with a 4 point lead over Mr. Romney in the latter's home state of Michigan. This ad re-enforces many voters' belief that Mr. Romney is not a true conservative and, more than any debate performance by either candidate, may help bring about the biggest upset of the primary season thus far.
