Virginia has made a total 180 in less than 10 years
Virginia used to be one of the most reliable R states in Presidential elections. Clinton never won the state. It was the only former Confederate State that Jimmy Carter didn't get in 1976.
I'm not sure that it has quite turned 180 degrees. It is close to the national average. I am not sure that the 8% margin for President Obama is valid, but the challenge of someone on the Right as a meaningful alternative to Mitt Romney (Constitution, Libertarian, Conservative) looks like an unmitigated disaster for Romney.
Conservative third-party alternative candidates could swing such states as Arizona, Georgia, Missouri, and Montana and cause the President to hold onto Indiana and one of the districts of Nebraska.
