Article Photos: Shifting landscape as Brown mulls Mass. Senate run 1/3

FILE - In this Nov. 4, 2012, file photo, then-Sen. Scott Brown, R-Mass., waves to supporters from his bus after a campaign rally at Faneuil Hall in Boston. Three years ago, Brown was a little-known Republican state senator from Massachusetts who shocked Democrats by winning a U.S. Senate seat. Now, having compiled a voting record more moderate than his tea party allies would have liked and losing his bid for a full term, Brown is considering whether to seize a second chance to return to the Senate in another special election.
