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.
