Romney's Free and Strong America political action committee announced the endorsement of businessman and mayor Paul LaPage in the battle for Maine's open gubernatorial contest. Republicans hope to win back the governor's office, which has been held for eight years by Democrat John Baldacci, who is prevented by term limits from running for re-election.
The PAC also endorsed businessman Jason Levesque in the race for Maine's second congressional district, and businessman Dean Scontras for the state's first congressional district.
"These endorsements are another in a series of state rollouts of the PAC's 2010 endorsements, which are aimed at electing conservative candidates who will work to lower taxes and spending, restore commonsense principles to healthcare and get our economy moving again," says a statement from the PAC.
"This coming election is going to yield some great wins for the Republican party and Governor Romney believes that the candidates we have running, not only in Maine but around the country, are among the most talented our party has seen in a very long time," says Romney spokesman Eric Fehrnstrom.
The endorsements appear to be part of a strategy for Romney to build support among Republicans across the country, in advance of what may be another bid for the White House. Romney's endorsements of Nikki Haley in the South Carolina GOP gubernatorial primary, and of former Gov. Terry Branstad in the Iowa Republican gubernatorial primary, could help him next year in those two crucial early voting states in the presidential primary calendar.
