As midterm election campaigns continue to unfold, Elizabeth Warren is a model of ubiquity. There's nowhere she won't go to boost Democrats -- from the liberal coasts to the upper Midwest to the conservative Appalachian precincts of coal country.
Candidates from West Virginia and Kentucky, states where a visit by President Obama could doom Democrats’ prospects, are calling after Warren. Sure, she is an unabashed supporter of Obama and Democratic leaders in Congress. (Progressives now identify themselves as part of the “Elizabeth Warren wing” of the party.) Her backing of the administration’s new regulations on carbon emissions, for example, puts the Massachusetts senator at odds with many voters in those states.
