Romney Rushes to Defend Michigan

With Rick Santorum surging ahead of Mitt Romney in the polls, the former frontrunner is returning to defend his home state. On Tuesday his campaign bought up nearly $1.3 million in airtime, and the pro-Romney super PAC Restore Our Future is bankrolling a new ad attacking Santorum. Romney also wrote an op-ed in The Detroit News defending his early opposition to the auto bailout. Both sides have been trying to lower expectations, with Romney saying he doesn't expect Michigan “to be a landslide,” and a Santorum adviser saying that the campaign is “under no illusions” that a win is likely.
