It's amusing to see Virginia listed as a GOP state.
How is this being assessed? Just how the state voted relative to the nation as a whole? If that's the case, there should be more states in the Democrat column. The GOP has only won the popular vote once in the last 6 elections, so the country by default leans Democrat in Presidential elections and therefore voting at about the same percentage as the nation would make a state a lean Democrat state.
This scale reads states when the election is completely tied. The states can still be leaning republican and vote for a democrat or vise versa. This system makes it fair to both sides and it's based purely on numbers.
Second, I'm not going to take affect the opinion that the country leans democratic. Times come and go and things change. Just because a republican or democrat wins an election doesn't mean the nation swings one way. There could be flaws in a candidate (Mitt Romney) or a terrible incumbent (Jimmy Carter), or other factors that determine the number a votes a candidate will get, even in their own party. You can never really tell when the nation really leans republican or democratic because of this. The country won't elect democratic presidents forever, no matter how confident you or anybody else might think.
If you want me to do a list that's based just on the margin of victory for 2012 then I will do it, but what I did was based on trend compared to the country.
