Memo to Democrats: Your 2008 coalition is coming apart at the seams. Half of your own party has already grown weary of Hope'n'change:
Democratic voters are closely divided over whether President Barack Obama should be challenged within the party for a second term in 2012, an Associated Press-Knowledge Networks Poll finds.Among Democrats, 47 percent say Obama should be challenged for the 2012 nomination and 51 percent say he should not be opposed. Those favoring a contest include most who backed Hillary Rodham Clinton's unsuccessful faceoff against Obama for the 2008 nomination. The poll did not ask if Democrats would support particular challengers.
A real Democratic challenge to Obama seems unlikely at this stage and his re-election bid is a long way off. But the findings underscore how disenchanted his party has grown heading into the congressional elections Tuesday.
