Michael Barone's latest Washington Examiner article dissects new data associated with voters' support for the two major parties. The Democratic party identification edge has been reduced to 47 to 43 percent. That's a 4-point drop for Democrats and a 4-point rise for Republicans since 2008. The Pew analysts note, as if they were analyzing a growth stock, that the Republicans' numbers haven't improved since 2010. But the 2010 numbers yielded a 52 to 45 percent Republican lead in the popular vote for the House. If -- and it's always a big if -- Republicans can maintain that standing in party identification, they should be in fine shape in November 2012, even with increased presidential year turnout.
