Elizabeth Warren: She's earned our support in Tuesday's election.The act of electing an “independent Republican” to represent Massachusetts in the United State Senate two years ago was, in some ways, a worthwhile exercise. Senator Scott Brown sometimes rejects the far-right majority that has become the brain trust and base of the Republican party. And he satisfies a certain instinct within our electorate to add variety to the range of political perspectives we have in our arsenal. But in a Republican party that no longer boasts even the modest makings of a moderate wing, Brown has been — and, unfortunately, will remain—a follower, an afterthought, an outlier with little sway in the national debate moving forward. Moderate Republicans have been driven from the ranks by Tea Partiers and other hard-liners whose allegiances to far-right ideologues (see Grover Norquist and his no-taxes pledge) trump any reasoned attempt at compromise.
