Have we've hit a tipping point now when it comes to same-sex marriage? That same tipping point that Argentina hit in 2010 when it approved same-sex marriage. Or Brazil in 2011. Or Canada in 2005. Or the Netherlands, Brazil, Mexico, Iceland, Sweden, Spain, South Africa, Portugal, and Belgium - all nations that have already recognized same-sex marriage in the last decade. That tipping point is best seen in the eight states that have passed laws to legalize same-sex marriage - with Maryland being the most recent earlier this year. VP Joe Biden was reflecting the mood in America - which is that we, as a nation, are ready to extend civil rights to all Americans regardless of their sexual orientation. Will President Obama come out in support of gay marriage before or after the election?
