Breaking: Specter intends to switch parties

Veteran Republican U.S. Sen. Arlen Specter of Pennsylvania intends to switch to the Democratic Party today or tomorrow, sources say. The switch would put Democrats one step closer to a 60-vote filibuster-resistant majority.

Update: Statement from Sen. Blanche Lincoln:

“Senator Specter is a highly respected colleague with whom I have had the pleasure to serve alongside in the Senate Special Committee on Aging. He has been a leading advocate for health care research funding, and I am proud to work with him in his efforts.

“Senator Specter’s party affiliation will not change his views or how he represents his constituents of Pennsylvania. I am a testament to the fact that the Democratic Party embraces a variety of viewpoints. I welcome Senator Specter to our diverse party, where I know his voice and his ideas will add to the spirited debate on issues critical to our country.”
