The agenda is set. President Obama gave his State of the Union address this week, and he was clear: He wants a year of action, and he’ll go it alone if Congress won’t go with him.But with Midterm Elections driving the political calendar and 2016 coming on fast – did the President lay groundwork for Democrats to succeed or openings for Republicans to attack?
