Barack Obama is leading John McCain 47 percent to 41 percent with 4 percent choosing neither and 6 percent undecided, in a Wall Street Journal/NBC News poll conducted July 18-21. The margin of error is 3.1 percent. Obama's lead is the same as it was in this poll last month.

Obama held his lead even though voters, by a 55 percent to 35 percent margin, said he was the riskier choice for President.
