From McClatchy-Marist, we have this shocker: Palin picks up 16 points on Obama.

A new McClatchy-Marist poll finds that Obama looks increasingly vulnerable in next year’s election, with a majority of voters believing he’ll lose to any Republican, a solid plurality saying they’ll definitely vote against him and most potential Republican challengers gaining on him.

Even in potential matchups where he leads, Obama in most cases has lost ground to the Republican.

The biggest gain came for Palin, the former Alaska governor who hasn’t yet announced whether she’ll jump into the fast-changing race for the 2012 Republican presidential nomination.

After trailing Obama by more than 20 percentage points in polls all year, the new national survey, taken Sept. 13-14, found Palin trailing the president by just 5 points, 49-44 percent. The key reason: She now leads Obama among independents, a sharp turnaround.
