Scott Brown's farewell speech hints at comeback

Scott Brown.

Sen. Scott Brown, the Massachusetts Republican who lost his re-election bid this November in a costly race against Democrat Elizabeth Warren, hinted on the Senate floor that he could soon be back in Washington.

"As I've said many times before, victory and defeat is temporary," he said in his farewell speech. "Depending on what happens, and where we go, all of us, we may obviously meet again, but I'm looking forward to continuing on with those friendships, with continuing on working with my staff."

Brown similarly said "defeat is only temporary" in his November concession speech.

The Republican was elected to represent Massachusetts in a 2010 special election after the death of Democratic Sen. Ted Kennedy. Even though Massachusetts is a solidly blue state, the 2012 Senate battle was one of the most expensive and contentious congressional battles of the year. Even though he lost, Brown's popularity remained high through Election Day.

Brown said today he doesn't know what his future holds, but there has been plenty of speculation about his future political prospects. If President Obama were to appoint Sen. John Kerry, D-Mass., to his cabinet in his second term, Brown could potentially run for that seat. Alternatively, he could run for governor in 2014.
