Brown made many tough and brave votes for GOP and Marxist Liz Warren used those to knock him off in the most lib state.
When I heard a certain radio talk show host claim that Marxist Warren beat Brown because he wasn't conservative enough (insane logic) I understood why Christie did whatever he could to get re-elected,
Look at the thanks he would get if he lost his election.
Doing what you have to do in a blue state to get elected is one thing. Taking a sanctimonious attitude with senators from red states ( Paul and Cruz ) about being too conservative is unacceptable.
