Romney's Announcement Day

Former Massachusetts governor Mitt Romney will officially launch his presidential campaign later this morning. He's holding a kick-off event in his home state of Michigan, and will travel to Iowa, New Hampshire, South Carolina, and Massachusetts over the coming days.

While Romney has been gaining in early polls, and he is attracting support from party activists, there are still many unanswered questions about his presidential viability.

Joining WBUR's Bob Oakes to attempt to answer a few of those questions is Newsweek Contributing Editor, and political analyst Eleanor Clift.

The audio for this story will be available on WBUR's web site after 10 a.m. on Tuesday.
