A conservative Republican organization says its 2015 national convention will be held in Maine. The Republican Liberty Caucus says the convention will be held at the Holiday Inn by the Bay in Portland. Caucus officials say Maine Gov. Paul LePage wrote a letter in December encouraging the organization to award the convention to Portland. In all, four cities expressed interest in hosting the event, which is held every other year. Previous RLC conventions have been held in the Washington, D.C. area: Gatlinburg, Tenn.: Las Vegas: Atlanta: Fresno, Calif.: Orlando, Fla.: and Jacksonville, Fla. The 2013 convention is slated for Austin, Texas. The caucus describes itself as a volunteer grass-roots wing of the Republican party that favors small government and individual liberties.
