The three NBC/Marist polls over sample Democrats and Ind. Democrats made up 31% to Republicans 26%. So it's clear the numbers will favor Obama by far. Independents made up 43%. Independents haven't even made up more than 30% of Virginia statewide voting the past two election cycles.
These polls also bank on the fact that we will see voting demographics close to 2008 election when we saw massive Democratic turnout. Voter enthusiasm this time around is going to favor Republicans as they are more enthusiastic about voting.
And no...it's not just one poll showing Romney leading. It's just you only hear about Obama leading polls in the media. Another poll of likely voters released on Tuesday had Romney up 5 points in Virginia
Bottom line is...all polls are BS and we know that based on past elections. Before the recall vote of Scott Walker the polls indicated he would lose.
