Michigan's Spencer Abraham to be national Fred Thompson chairman

Michigan has a favorite son--Spencer Abraham-- who will be one of the heads of Fred Thompson's campaign to win the Republican nomination for President next year. 

Question:  Is this a shrewd move on the part of Thompson or is it a sign that he's not to be taken seriously?

Why do I ask?  Abraham gave away his seat in the U.S. Senate to incumbent Debbie Stabenow.

Here's what Tennesseans For Thompson said on their blog:

Meanwhile, new campaign manager Enright

will be joined by a new National Campaign chairman, former Michigan Senator and Energy Secretary Spence Abraham. Tom Collamore will remain a senior adviser to the campaign, as will Mark Corallo and several other unofficial Thompson campaign staffers.
