While it's too early to say support for marriage equality for gays and lesbians is the majority
opinion in the U.S., it's become clear in recent polling results that opposition to allowing same-
sex couples to marry is now a minority position, writes Nate Silver. "The trendline -- derived
through regression smoothing -- estimates that about 50% of Americans now support gay marriage and that 46% are opposed, with a small percentage of voters undecided," he writes.
