Former Alaska Governor and Tea Party favorite Sarah Palin on Thursday endorsed Sean Bielat in an increasingly tightening race against Massachusetts Congressman Barney Frank.

In her endorsement, Palin reminisced that it was January 2010 in Massachusetts, a reference to the come-from-behind win of conservative Republican Scott Brown.

“Sean is a businessman, Marine veteran, and young father, and he is running against an ethically-challenged liberal icon who opposed reform of Fannie and Freddie before the meltdown. That's right, Sean Bielat is running against Barney Frank, and he needs your help to win,” Palin said on her Facebook page.

Bielat is opposed to repeal of “Don't Ask, Don't Tell,” the Clinton-era law that forbids gay and bisexual service members from serving openly, and gay marriage. Massachusetts became the first state to legalize the institution five years ago.

Frank, who is openly gay, remains ahead in the polls, but several surveys show Bielat closing the gap between the two candidates.

Palin, a rumored 2012 presidential hopeful, previously endorsed Delaware candidate for the U.S. Senate Christie O'Donnell, who gay baited her Republican rival, Rep. Mike Castle, during the GOP primary and recently defended the military's gay ban. In August, Palin spoke to an anti-gay group in Pennsylvania, and she also endorsed anti-gay Karen Handel in her bid to become Georgia's next governor. Handel, who recently said she would “absolutely” consider a bill that prohibits gay and lesbian couples from adopting children, lost her bid for the GOP nomination.
