WASHINGTON (Reuters) - Democrat Barack Obama's lead over Republican rival John McCain has grown to 12 points in the U.S. presidential race, with crucial independent and women voters increasingly moving to his side, according to a Reuters/C-SPAN/Zogby poll released on Thursday.

With less than two weeks before the November 4 election, Obama leads McCain 52 percent to 40 percent among likely voters in the latest three-day tracking poll, which had a margin of error of 2.9 points.

Obama has made steady gains over the last four days and has tripled his lead on McCain in the past week of polling.

"Obama's expansion is really across the board," pollster John Zogby said. "It seems to be among almost every demographic group."
