Obama leads 47-42, down from 50-42 in the same poll from March.

That’s in line with the Real Clear Politics average of polls, although a survey from conservative polling outlet Rasmussen released this week showed the two candidates tied in Virginia.

Obama’s lead would still be 5 points even if Romney were to add Virginia Gov. Bob McDonnell to the ticket. McDonnell is frequently mentioned as a potential Republican vice presidential candidate.

While Romney has made inroads among female voters nationally, women continue to buoy Obama in Virginia, where he leads 51-35. Romney has a 5 percent lead among men in the state.

Obama also leads 45-37 among independents in Virginia. Independents have so far tended to favor Romney nationally.
