Senator Susan Collins (R-ME) meets with the President Obama in the Oval Office. Collins was one of three Republican Senators who eventually voted for the stimulus bill.
Described as one of "the last survivors of a once common species of moderate Northeastern Republican,"[5] Collins is considered a bipartisan and centrist member of the Republican Party, and an influential player in the U.S. Senate.[9][10][11][12] She is a member of several moderate organizations within the Republican Party, including the Republican Main Street Partnership, Republican Majority For Choice, Republicans for Choice, The Wish List, Republicans for Environmental Protection, and the Republican Leadership Council. Her voting record was at one time center-left which has caused some Republicans to label her as a "Republican in Name Only" (RINO). Although she shares a centrist ideology with Maine's senior Senator, Olympia Snowe, Collins is considered a "half-turn more conservative" than Snowe.[5] Collins has consistently been endorsed by the Human Rights Campaign, a major LGBT rights organization; she was one of six Republicans running in 2008 to be endorsed by the HRC.[13] She supported John McCain in the 2008 election for President of the United States.[14]
In the 1990s, Collins played an important role during the U.S. Senate's impeachment trial of Bill Clinton when she and fellow Maine Senator Olympia Snowe sponsored a motion that would have allowed the Senate to vote separately on the charges and the remedy. When the motion failed, both Snowe and Collins subsequently voted to acquit, believing that while Clinton had broken the law by committing perjury, the charges did not amount to grounds for removal from office.
