Democrat Barack Obama has built a 4-point lead over Republican rival John McCain in the White House race, aided by growing support from women and independents, according to a Reuters/C-SPAN/Zogby poll released yesterday.

Obama led McCain 48 percent to 44 percent among likely US voters in the daily national poll, up from a 2 percentage-point advantage on Wednesday. The poll has a margin of error of 2.8 percentage points.
