Gay marriage passing in Maryland, Maine, Minnestona, and Washington is proof USA is no longer a Christian nation. It's also significant in showing that the polls are right. The majority of Americans do support same-sex marriage and 2012 is the tipping point for the issue.
The 2012 election in USA was the most liberal electorate in US history. The right wing extremists in USA were voted out of office.(Todd Akin, Allen West, Joe Walsh, Richard Mourdock, etc.) Obama's established the most brilliant campaign in US history a collation of women, black, Latino, Asian, young voters, LGBT, workers, liberals, progressives, moderates, etc.
I have to tell you that was probably the proudest day I have felt to be an American in a long time. Things are changing in the USA for the better.
