Must say it was bittersweet to watch this video as that was a special time to be in Massachusetts. The Tea Party was fully behind Scott Brown at that time but they aren't that enthused about him anymore.
Half the voters of Massachussetts live within the 128 belt around Boston. The yard signs there for Warren are plentiful, not so for Brown. Brown yard signs dominate the rural areas outside of Greater Boston. I would guess Warren dominates the other cities throughout Massachusetts. The numbers are just not there for Brown. He thumbed his nose at the Tea Party who put him in office two years ago.
