Trump to dial into Michigan for Romney

ABC News reports that the Mitt Romney campaign is deploying Donald Trump as a surrogate in radio interviews in Michigan:

Trump’s effort begins Monday morning with an interview on the “Art Lewis Show,” on WSGW news radio in the Flint-Saginaw media market. On Tuesday he will call into the “Ron Jolly Show” on WTCM in Traverse City. On Wednesday it’s the “Paul Smith Show” on WJR in Detroit. And on Thursday, Trump will talk to Michael Patrick Shiels, host of a drive-time radio program on WJIM in Lansing.

Trump has been hitting Rick Santorum hard, as he's praised Romney. Santorum told Fox News' Greta Van Susteren recently that he called Trump to discuss some of his criticisms.

Romney's campaign aides said they're arranging the interviews for Trump. Trump adviser Michael Cohen said, "When Mr. Trump elected to endorse the governor, it's wasn't a mere symbolic gesture, it was legitimately an offer to help in any way possible, and as the governor continues to ask, Mr. Trump will look to comply."

Romney is making an all-in push for his native state, as polls show a tight contest there with Santorum, and as his campaign has called Michigan a must-win to supporters.
