If Rick Santorum is looking to the April 24th Pennsylvania primary to give him a much needed home-state victory, this might throw a monkey wrench into things:
Republican Mitt Romney will air presidential campaign ads in most of Pennsylvania starting on Monday, when candidates return from their Easter break, a source close to the campaign said on Friday. The $2.9 million advertising campaign will run in the Wilkes-Barre, Scranton, Erie, Altoona and Philadelphia media markets until the April 24 primary election. Within a week, the ads will run in the Pittsburgh market. The Romney super PAC Restore Our Future is airing commercials on cable channels statewide. (source)
It’s a pretty clear warning shot from the Romney campaign to Santorum: Drop out now, or risk being embarrassed in your home state.
