Romney in Detroit with new message: 'This is personal'

It's a must-win contest for Romney, but the Detroit native trailed Rick Santorum in two polls of the state released Monday. Santorum has said he and his campaign will "plant our flag" in Michigan and compete hard for delegates there. The state is far from a sure thing for Romney, as his campaign's decision to spend there shows.

"When I grew up in Michigan it was exciting to be here. I remember going to the Detroit auto show with my dad. That was a big deal," he says in the ad as images of Detroit in the 1960s and pictures of him as a young man in Michigan are juxtaposed with video of the city today. "How in the world did an industry and its leaders and its unions get in such a fix that they lost jobs, that they lost their future?

"President Obama did all these things the liberals have wanted to do for years, and the fact that you've got millions of Americans out of work, home values collapsing — people here in Detroit are distressed."
