Former Rep. Chris Shays (R-Conn.) will run for the Senate, according to Greenwich Time, a local newspaper.
Shays, who had sold his home in Connecticut and moved to Maryland after he was defeated by Rep. Jim Himes (D-Conn.) in 2008, has moved back to the Nutmeg State with his wife Betsi, and recently re-registered to vote in the state.
The seat will be open: Sen. Joe Lieberman (I-Conn.) has decide to retire. The state is strongly Democratic and has not had a Republican senator since 1988, although centrist Republicans have run well there and the state had a Republican governor from 2004 through 2010.
Shays will likely face former World Wrestling Emporium CEO Linda McMahon, who lost a 2010 Senate race, in a Republican primary. McMahon spent $50 million on that race only to lose to now-Sen. Richard Blumenthal (D-Conn.) by a 12-point margin.
The Democratic field is as yet unsettled. Candidates include former Connecticut Secretary of State Susan Bysiewicz, Rep. Chris Murphy (D-Conn.) and state Rep. William Tong.
