Lincoln D. Chafee

Lincoln Chafee, former U.S. senator from Rhode Island, was often called the most liberal Republican in the Senate. In office, he bucked his party on a number of hot-button issues, including same-sex marriage and the war in Iraq. His book Against the Tide challenges the Republican Party on its rightward drift.

Sen. Lincoln Chafee (R-RI) is serving out his term after being ousted by Democrat Sheldon Whitehouse in the midterm elections. Considered to be the most liberal Republican in the Senate, Chafee is the only one to have voted against the war in Iraq. He made another notable split with the GOP when he opposed the nomination of John Bolton as Ambassador to the United Nations.
