Former Massachusetts Gov. Mitt Romney trails President Barack Obama by eight points in a poll of Virginia voters by Public Policy Polling.

PPP released the poll results Tuesday; Romney is visiting a company in Chantilly Wednesday on a campaign stop.

Obama leads Romney 51 – 43 percent, up slightly from PPP’s poll in December when Obama led by six points (48 – 42). In the late April poll, 6 percent of respondents said they were undecided.

PPP surveyed 680 Virginia voters through an automated telephone interview system from April 26 to April 29. The margin of error for the survey is +/-3.8 percent.

“We have polled Virginia six times this election cycle and have found Barack Obama with a decent sized lead over Mitt Romney every single time,” said Dean Debnam, president of Public Policy Polling, in a research release. “Barring a big shift in the political climate Virginia is likely to go for Obama again, and that’s going to make it very hard for Romney to score a victory in the electoral college.”

Romney, the likely Republican presidential nominee, will visit Exhibit Edge on Walney Road in Chantilly at 10 a.m. Exhibit Edge is a company that provides services and support to the trade show industry.

Republican Newt Gingrich also may be in Northern Virginia on Wednesday to officially announce his departure from the presidential race, according to CBS News. The PPP poll showed a strong majority of surveyed Virginia voters have an unfavorable view of Newt Gingrich.
