(NECN: Alison King) - Massachusetts Senator Scott Brown will be the man to beat in 2012, when he is up for re-election. Brown made history when he defied all odds and was elected to Senate last year.
It's been almost a year since republican Scott Brown stunned the political world with his upset in the Massachusetts U.S. Senate race.
Since then he has been what he said he would be: unpredictable.
While he certainly votes a majority of the time with his party, he has also given some key votes to the democrats.
All this is being evaluated as possible 2012 challengers contemplate whether or not to take on the state's most popular politician.
And with Scott Brown's war chest at $7-million dollars and growing -- analysts say interested Democrats should be deciding soon.
So who are these interested Democrats and do they have what it takes to win?
