Former Rhode Island Governor Lincoln Chafee is who SFGN is keeping tabs on in this week’s edition of White House Watch. The 62-year-old Rhode Island native was once called America’s No. 1 RINO (Republican In Name Only) but has since joined the Democratic Party.

Chafee announced last week he was exploring a possible campaign for the U.S. Presidency, but it remains unclear if he has filed papers with the Federal Elections Commission (FEC). If Chafee runs, he would join former U.S. Secretary of State Hillary Clinton in the Democratic field. Chafee is already on record as saying Clinton is “a little too close to Wall Street.”

Chafee’s political career is often referred to as an odyssey. He served in the U.S. Senate as a Republican, appointed to the seat after the sudden death of his father, John Chafee. As a Senator, Chafee earned his RINO reputation by refusing to get in line behind then President George W. Bush’s wartime agenda and blasting the Bush administration over environmental policies.

In 2011, Chafee won the Rhode Island governorship as an Independent but abandoned re-election plans in the face of low approval ratings. He officially switched to the Democratic Party in May of 2013, the same month in which he signed into law same-sex marriage in Rhode Island, the nation’s smallest state.

“I am considering a run for the Presidency so that we can better direct our energies toward an age of lasting peace,” Chafee says in a video message on his website chafee2016.com
