Of course, Republican caucus-goers are likely to be much more conservative, but Iowans, in general, don't seem too worked up about gay marriage: More either favor it or don't care than actually oppose it.
Do you favor or oppose the recent Iowa Supreme Court decision that allowed gay and lesbian couples to marry in Iowa?
26% Favor, 43% Oppose, 30% Don't care much
If a vote on a constitutional amendment to ban gay marriage were helf today, how would you vote?
41% Yes to ban
40% No to continue
17% Would not vote
And in the most telling number of all -- 92% of Iowans say gay marriage has brought no real change to their lives.
