Democrats took aim Thursday at Republican congressional hopeful Bruce Poliquin for his “tacit endorsement” of a conservative Christian political group that remains deeply opposed to the legalization of gay marriage almost a decade ago.

Poliquin is slated to help with a December candidate training session, put together by the Christian Civic League of Maine, a politically active group that declared the Republican National Committee’s recent decision to form a new RNC Pride Coalition, “threatens to undermine the GOP’s pro-faith and pro-family values.”
