U.S. Sen. Olympia Snowe, R-Maine, flanked by her husband former Maine Gov. John R. McKernan Jr., prepares to place her ballots in the electronic reader after voting Tuesday morning at Falmouth High School. This was her last Election Day vote as Maine's senior U.S. senator; after more than 30 years in Congress, including terms as a U.S. representative, Snowe, 65, is not seeking re-election.
