GRAND RAPIDS (WKZO) -- Congressman Justin Amash of Grand Rapids is reportedly thinking about running for the U.S. Senate.  National Review reports the Republican is "privately" considering a run, but only if Democrat Carl Levin decides to retire.

Levin is Michigan's senior U.S. Senator and chairs the Senate Armed Services Committee.  The 78-year-old has not yet decided if he will seek another term.
