The Maine State Chamber of Commerce is paying tribute to U.S. Sen. Olympia Snowe. The chamber is commemorating Snowe’s 34 years in Congress at its annual dinner on Friday at the Augusta Civic Center. The program will feature an award presentation and remarks by Snowe and her husband, former Maine Gov. John McKernan. Snowe announced last winter she is not seeking re-election to a fourth term in the Senate because of what she called political polarization in Washington.
