"We need to come together to rein in the growth of government not only to preserve Maine’s unique way of life, but to protect our freedoms," Thibodeau said in his campaign announcement. "We need to continue to improve our economy, create more jobs, and educate our children so they can live and work here at home.”

Thibodeau joins three other conservatives in the Republican primary -- House GOP leader Ken Fredette, Senate GOP leader Garrett Mason and former DHHS Commissioner Mary Mayhew. Moderate and former independent Shawn Moody says he is also giving serious consideration about entering the Republican primary race.
