As a bit of time has passed since U.S. Senator Carl Levin’s announcement that he will not seek re-election in 2014, the field of both Democratic and GOP contenders is just beginning to take shape – mostly as some make clear their intentions not to run.

This week, Scott Romney added his name to those not seeking the office, which also includes current Michigan Attorney General Bill Schuette.

Names that remain in discussions include Lt. Governor Brian Calley, State Senator Roger Kahn (R-Saginaw), and State Representative Pete Lund (R-Shelby Township); however, those leading the same discussions at the moment appear to be U.S. Congressman Mike Rogers (R-Brighton), U.S. Congressman Justin Amash (R-Kentwood) and former Secretary of State and Republican National Committeewoman Terri Lynn Land.

Meanwhile on the Democratic side, the path currently appears to be paved for current U.S. Congressman Gary Peters (D-Bloomfield) as other Democratic office holders line up in support.

State Superintendent of Public Instruction Mike Flanagan has indicated that he is also considering a run.
