Two polls today show Barack Obama leading Hillary Clinton in North Carolina, but by smaller margins than earlier.

For the other state that votes next Tuesday, Indiana, one poll out today shows Clinton ahead by 8.

Obama’s North Carolina lead is 51 percent to 37 percent, according to a Rasmussen Reports poll conducted April 28. The margin of error is 4 percent. In a survey Rasmussen conducted April 3, Obama had led by 23 points. Clinton’s numbers are helped by her 2-to-1 lead over Obama among white voters making less than $60,000 a year and among white voters in general, where her margin is 15 points. Obama’s favorability rating among likely voters is 71 percent compared to 62 percent for Clinton. Thirty-two percent say Clinton should drop out and 20 percent say the same about Obama. Both candidates are close when voters are asked who would have the best chance against John McCain in November – 89 percent say Obama while 84 percent say Clinton.

A SurveyUSA poll conducted April 26-28 shows the race becoming closer than Rasmussen’s results showed, with Obama ahead by 49 percent to 44 percent, having what was once a 10 point advantage. There are 3 percent undecided and a 3.7 percent margin of error. Clinton now has her largest lead among white voters in this poll, beating Obama by 2-to-1. They make up 61 percent of the sample. Obama leads among black voters (33 percent of the sample) by 87 percent to 11 percent.

A Public Policy Polling survey released yesterday had Obama’s one-time 25 point margin down to 12. American Research Group had Obama’s lead at 10 which it said was unchanged from its previous poll.
