It'll be a small one. Idaho fits the bill. Heavily white male, and without any big urban centers to really push the issue.
I think it'll likely be nationalized, either by the Supreme Court or by consensus during a moderate Republican Admin. The Republicans would likely block it during a Dem administration, but the push of the public might work better under someone like Christie.
I think Idaho is more likely to support it than Alabama(White & very southern), since North Idaho is pretty socially liberal & Boise is becoming "heavier" in the state.
