When will your state VOTE FOR gay marriage?

From the brilliant mind of Nate Silver over at FiveThirtyEight.com, we have a regression model predicting the likelihood of a state voting to legalize (or to not illegalize, rather) gay marriage. Good news? By 2012, almost have the states in the union, based on polling trends, would vote in favor of equality. Bad news? By 2012, Iowa would lose that fight 50.6 to 49.4.

2012 is the very earliest a constitutional amendment could go to the voters in Iowa to overturn the Supreme Court's decision to legalize marriage.

As a note, Ohio's equal marriage ban -- Issue 1 in 2004 -- only passed by 55-45 or something similar. That's really close for Ohio.

Of equal importance, perhaps more, he makes this comment about the data:

All of the other variables that I looked at -- race, education levels, party registration, etc. -- either did not appear to matter at all, or became redundant once we accounted for religiosity. Nor does it appear to make a significant difference whether the ban affected marriage only, or both marriage and civil unions.

Did you hear that? The only major variable that matters is religion. I'm sure there's a point there somewhere.
