WASHINGTON (AP) - An Associated Press-Knowledge Networks Poll finds that Democratic voters are closely divided over whether President Barack Obama should be challenged within the party for a second term in 2012.
And the nation at large is equally divided over whether Obama should be a one-term president.
A real Democratic challenge to Obama seems unlikely at this stage and his re-election bid is a long way off. But the findings show how disenchanted his party has grown heading into the congressional elections Tuesday.
The AP-KN poll has tracked a group of people and their views since the beginning of the 2008 presidential campaign. Among all 2008 voters, 51 percent say he deserves to be defeated in November 2012 while 47 percent support his re-election.
