US presumptive Democratic presidential candidate Barack Obama picked up more support from women voters soon after his decisive win in the presidential nomination race, according to a poll released on Wednesday.

The Gallup poll conducted from June 5 to 9 showed that the Illinois Senator was supported by 51 percent of women voters, compared to 38 percent for his Republican rival, Arizona Senator John McCain.

Another poll conducted a week earlier showed Obama's lead over McCain in women voters' support by only 5 percentages.

The Gallup said that many older and married women voters shifted their support from Obama's former rival, Hillary Rodham Clinton, to him was a reason to explain his surge.

The matchup of McCain and Obama in winning the support from married women voters was used to be 52-40, but now changed to 45-45, according to the polling body.

It said that female voters had to take a second thought over Obama since their candidate, Clinton, was not in the race any more.

"Indeed, his current 13-point advantage over McCain is essentially the same advantage that Clinton held over McCain throughout her active candidacy."

Obama also saw his popularity growing among male voters.

In a newest Gallup poll, McCain's lead over Obama in male votes by 47 to 45 percent, compared to 49 to 43 percent in an earlier poll.
