Hyannis, Massachusetts (CNN) - Massachusetts Sen. Scott Brown rode into office two years ago as an everyman with a pickup truck, vowing to "take back the peoples' seat" held by Democrat Ted Kennedy for nearly half a century.

Here on Cape Cod, Brown's breezy persona persists as he strolls down Main Street, shaking hands, posing for pictures and playfully shouting to a passerby to keep her eyes on the road.
