Rep. Ron Paul's message during the contest for the Republican presidential nomination has been consistently that he's the true fiscal conservative while all the other contenders are fake.

Now Paul has Santorum in his sights, labeling him a "fake" fiscal conservative, indeed humorously using that icon of phoniness, Sasquatch, to drive home the point in a new ad running in Michigan. The ad could have some appeal in the Pacific Northwest, too, when the Republican caucuses rolls around in Washington State, the land of the legendary Bigfoot.
