This sets up as a double whammy for Obama on election day; reduced Black turnout and less support among young, and poor whites. The combination - if it works out that way - would make it extremely difficult for the president in some key states and complicate his road to 270 electoral votes.

The Note:

New analysis by Pew Foundation on voter identification finds that, not surprisingly, "the electorate's partisan affiliations have shifted significantly since Obama won office nearly three years ago."

One of the most notable shifts is the GOP gain among white voters, most specifically "the young and poor."

"A seven-point Democratic advantage among whites under age 30 three years ago has turned into an 11-point GOP advantage today. And a 15-point Democratic advantage among whites earning less than $30,000 annually has swung to a slim four-point Republican edge today."

The last time that Republicans had this level of support among young white voters was 2002-2004, which was, of course, the wake of the 9/11 attacks.

Obama's three key constituencies in 2008 were under 30, those making less than $30 thousand, and college educated whites. To be behind in two of those constituencies at this point should have them burning the midnight oil at the White House.
