Obama's State of the Union doesn't bode well for his coalition

The New Republic reports:

There are two keys to achieving real political dominance for the new Obama coalition. First, it must be mobilized beyond presidential elections—in congressional elections, where turnout patterns don't yet align very closely with presidential elections, and between elections, in the struggle to achieve legislative victories. Second, the Obama coalition must be widened to take in a larger share of the white working class. Otherwise, the hostility of these voters will undercut public support for the president’s agenda, as well as remaining a lurking threat in every election, particularly congressional ones.
