The 2008 United States Senate election in Maine was held November 4, 2008. Incumbent Republican U.S. Senator Susan Collins won re-election to a third term.
Allen tried to connect Collins to George W. Bush, but these tactics failed as Collins maintained her image as a very popular, moderate, independent Republican. She obtained an endorsement from Independent and former Democratic U.S. Senator Joe Lieberman.[1]
