US Democratic presidential candidate Barack Obama has opened up a 10-point lead over Republican opponent John McCain two weeks before the November 4 US election, according to Wall Street Journal/NBC News poll released on Tuesday.

The poll found 52 percent of voters favor Obama compared with 42 percent for McCain, up from a 6-point Obama edge two weeks ago, the Wall Street Journal reported.

The 10-point lead is the largest in the Journal/NBC poll to date and represents a steady climb for Obama since early September, when the political conventions concluded with the candidates in a statistical tie, the newspaper reported.

The poll also found that the popularity of Alaska Gov. Sarah Palin has fallen. Voters are less likely to see the Republican vice presidential nominee in a positive light, and much more likely to report negative feelings, the Wall Street Journal said.

Forty-seven percent view Palin negatively, compared with 38 percent who see her in a positive light.

Fifty-five percent of voters say Palin is not qualified to be president, up from 50 percent two weeks ago.

The poll of 1,159 registered voters was conducted from Friday to Monday and has a margin of error of plus or minus 2.9 percentage points.
