I guess he has not received the talking points

Senator Scott Brown, a Massachusetts Republican, was noncommittal. “He will review the compromise, and while the proposal may not be ideal, he wants to make sure that it is good for American families and a victory for taxpayers,’’ said Gail Gitcho, the spokeswoman for the Massachusetts Republican.
while it seems the senior senator will be a good soldier, even if the article implies he is less than happy with the deal:
Senator John F. Kerry, a Massachusetts Democrat and a potential key vote, left open the possibility of supporting the measure. “We have a huge amount here that will go to working people, that goes to average Americans,’’ Kerry said after emerging from the Democratic meeting, noting a reduction in certain payroll taxes. “The middle class is going to get tax cuts that we never contemplated that we could get.’’
"Left open" does not imply a ringing endorsement.
Even Stephen Lynch dislikes the deal.
At least two members of the Massachusetts delegation announced their opposition, while others expressed reservations. Representative Barney Frank, a Newton Democrat, said he opposed the plan, while Representative James McGovern, a Worcester Democrat, called it “a lousy deal.’’ Representative Stephen F. Lynch, a South Boston Democrat, said he was “inclined to vote against a deal that equates the needs of long-term unemployed workers with individuals who earn over $200,000.’’
