President Obama’s approval rating dropped to 35 percent approval among Pennsylvania’s registered voters, according to the most recent Muhlenberg College poll. This is a state Obama carried in 2008 by 10.4 percent (54.7 percent v. 44.3 percent for John McCain). It is hard to envision a scenario in which Obama can win the presidency without Pennsylvania. The Keystone State, in fact, has voted for the Democratic nominee in every election since 1992. But right now, in the summer of his third year in office, Obama is almost 20 points below the percentage he won in 2008. I wonder how long this will go on before Democrats understand the Obama Era may turn out to be among the most brutal the Democratic Party has ever experienced.
