Actually, given the results of the last mid-term election, that is oversampled by roughly 7-points. The 2010 party identification numbers were split evenly amonst Dems-Republican 36/36 and 28% Indies, which I believe is one of the largest Indy representation in the modern era.
2010 Elections Exit Poll Analysis:
"Democrats and Republicans were at parity in self-identification nationally, 36-36 percent, a return to the close division seen in years before 2008, when it broke dramatically in the Democrats' favor, 40-33 percent."
Yeah cuz exit polls have been so reliable these past 10 or so years. Every time exit polls differ from REAL polls (i.e. the actual votes) dems scream the election was stolen. And the exit polls are always way off.
