The former Navy SEAL in interviews and a newspaper editorial last year strongly criticized Obama for using the SEAL raid that killed Osama bin Laden as a political talking point.

Republican state Rep. Daniel Winslow and former U.S. Attorney Michael Sullivan also are running.
Congressmen Edward Markey and Stephen Lynch are competing on the Democratic side.
