Former Rep. Nancy Johnson (R-Conn.) has switched sides to back state Sen. Sam Caligiuri (R) for her former seat. Caligiuri was running for Senate until a few weeks ago, when he switched races to run for Connecticut’s 5th House district.

There’s only one problem: Johnson had already endorsed Afghan War Veteran Justin Bernier for the seat, spoke at several events for him and hosted a reception at her Washington, D.C. home. Johnson told a local state newspaper that she was switching her endorsement because Caligiuri is a “better candidate…with a better chance of winning.”

Johnson held the seat for 12 terms until 2006, when Rep. Chris Murphy (D-Conn.) defeated her with 54 percent of the vote.

UPDATE: Bernier responded to say that Johnson never officially endorsed his campaign, although she did support him early on in his bid.

“Our campaign is focused on earning the support of the Republican town committees who select the Republican nominee for U.S. Congress,” Bernier wrote in a statement. “We will continue to build on our large lead in town endorsements.”
