Elizabeth Warren Optimistic About Tuesday

Scott Brown, meanwhile, has taken a more dour tone

Elizabeth Warren campaigned Saturday with the air of a winner, with her surrogates invoking the Kennedy name and alluding to the history-making potential to become the state's first female senator.

Scott Brown offered a more dour message, lamenting a country "in trouble" and alluding to "dirty tricks" by Democrats willing to do anything to cling to power.
