South Dakota's was bizarre how (honest question)? It was just restrictive and the 2006 mood in non-southern states just seemed to have shifted. Also, Oregon's vote was in 2004. I doubt Oregon currently opposes gay marriage more than Colorado. It may have even failed by this point.
I don't know....there seems to have been a balence forged.
In South Dakota. NO civil unions are allowed...not even for straight couples.
Also, according to Survey USA in 10/06-
Liberals and Conservatives- National average is 20-29 (according to the 2000 election)
Oregon- 21-26
Colorado- 20-29 - about a 4 point spread
Pro-Life - Pro-Choice
Oregon- 37-59
Colorado - 35-61 - about a -4 point spread.
There is also a 6 point spread between the places in party identification and indies approve of Bush slightly more in Colorado.
and Bush's approval was 38 in Oregon and 39 in Colorado.
