One in four Democrats wants to dump Obama

A new poll by CNN and ORC International finds that 27 percent of Democrats would like to see their party nominate a candidate other than Barack Obama for president in 2012.

In response to the question, "Do you think the Democratic party should renominate Barack Obama as the party's candidate for president in 2012, or do you think the Democratic party should nominate a different candidate for president in 2012?" -- 72 percent said they wanted to see Obama renominated. But 27 percent, slightly more than one in every four, said they wanted to see Democrats nominate a different candidate. One percent had no opinion.

The poll was taken August 24-25. In a survey taken in early August, 28 percent of Democrats said they wanted a different candidate. Polls taken in July and before showed Obama in a stronger position, with no more than 22 percent saying they preferred a different candidate. The current poll is based on interviews with 463 Democrats and has a margin of error of 4.5 percent.

The new poll is another indication of Democratic unhappiness with the president, but it does not mean Obama will face a challenge in his party's primaries. Despite the complaints of a few liberals like Sen. Bernard Sanders, the odds of a Democrat opposing the president appear to be something less than zero. But the new poll is still a matter of concern to Democrats, because it is yet another indication that there is significant disillusionment with the president within his own party. Whether those disaffected Democrats will come around to supporting Obama next year is an open question -- and perhaps the most worrying of the president's re-election bid.
