Obama ahead in N.C., statistically tied in Pennsylvania and Indiana

New polls for the next three Democratic contests show little evidence so far of any damage to Barack Obama from his comments about bitter small town voters.

The Los Angeles Times/Bloomberg surveys also suggest that Hillary Clinton has work to do in Indiana, which could end up being the tie-breaker if she wins Pennsylvania as expected and Obama wins North Carolina, where he is favored.

In Indiana, which votes May 6, Obama has a 5-percentage-point lead over Clinton, 40 percent to 35 percent, even though the state's demographics appear to favor her, according to the poll.

In Pennsylvania, which holds its primary this coming Tuesday, Clinton has a 5-percentage-point lead over Obama, 46 percent to 41 percent.

And in North Carolina, which also votes May 6, Obama leads by 13 percentage points, 47 percent to 34 percent.

The gaps in Indiana and Pennsylvania are within the polls' margin of error, and there are enough undecided voters in all three states to swing the races.

The surveys also found that Obama's handling of his controversial former pastor, the Rev. Jeremiah A. Wright Jr., might have helped him, with most voters saying they thought more highly of Obama.
