Manchester, New Hampshire (CNN) - New Hampshire State Senate President Peter Bragdon will endorse Mitt Romney on Thursday, CNN has learned.
The endorsement is the latest in a wave of support for Romney from high-profile legislative officials in New Hampshire. It comes as the former Massachusetts governor's campaign shifts into a more aggressive mode in the state, where former House Speaker Newt Gingrich has recently gained some steam.
Like Sen. Kelly Ayotte, who backed Romney last month, Bragdon is a conservative Republican who has signaled electability is a key factor in his choice for the GOP primary.
Romney has long led in the polls in New Hampshire and has picked up endorsements from two of three members of the state's federal congressional delegation and a string of other political notables.
Last weekend, however, Gingrich snatched up one of the biggest coups in the state, when the New Hampshire Union Leader backed him in the GOP primary.
Romney will campaign with supporter and former presidential candidate Tim Pawlenty on Saturday in Manchester.
