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.
