Colorado voters will be ready to repeal the state's constitutional ban on gay marriage next year, according to an analysis by voting statistics geek Nate Silver of FiveThirtyEight.com. Following the Iowa Supreme Court's establishment of same-sex marriage on Friday, Silver examined the trends in the 30 states that have voted on gay marriage bans and found that "while you might (not) know it from Proposition 8's victory last year, voter initiatives to ban gay marriage are becoming harder and harder to pass every year."
