Republican candidates for Connecticut Senate are dropping like flies. State Sen. Sam Caligiuiri (R) formalized his decision to switch from the Senate race to a 5th district House run on Tuesday. And businessman and former Ireland Ambassador Tom Foley (R) also disclosed that he is now looking at shifting from the Senate to the open seat governor’s race.

That leaves former Rep. Rob Simmons (R), former World Wrestling Entertainment CEO Linda McMahon (R) and libertarian investor Peter Schiff (R) to duke it out for the right to challenge embattled Sen. Chris Dodd (D) next year.

Caligiuri, who last week received public encouragement from Connecticut’s Republican party chair to consider the switch, said in a release Tuesday that he had concluded that other candidates in the GOP field “are in a better position than I am to defeat Senator Dodd.”
