Rick Santorum’s 2012 TV strategy: Winning on the cheap

Rick Santorum’s relatively meager war chest might be big enough to put up a serious fight in upcoming TV ad wars against Mitt Romney and his money machine. Santorum and his supporters are going to leverage the lineup of the next few contests, making ad buys in states where airtime is cheap and spending strategically to zero in on Santorum’s base of conservative voters in more expensive ones. That combination could pick him up enough delegates to continue fundraising and keep him in the race past Super Tuesday.
