Alas, I wouldn't hold my breath:
In total, 56 percent of respondents supported federal legal recognition of same-sex marriage while 43 percent opposed it.
The breakdown among party affiliation and generation is stark. Among those 18-34-years-old, 77 percent support federal recognition. Among those over 65-years-old, just 39 percent support it. Those in-between 34 and 65 hover around the 50 percent mark.
Along party lines, 75 percent of Democrats, 56 percent of independents and 28 percent of Republicans support recognition.It's a good bet that support for gay marriage among GOP state legislators is much lower than 28% at the moment. I don't know any current office-holders who even support repealing the ban, even if they might not be so sanguine about permitting gay marriage.
Priebus wants his party to have it both ways. Public opinion is increasingly saying that this isn't possible. I don't see someone like Glenn Grothmann changing his tune on the matter any time soon.
I'm unaware of a single state GOP legislator who supports repealing the marriage ban. This is an opportunity for Democrats in Madison to make Republicans own up to positions that are rapidly reaching their expiration date. It's not like they can do much more considering they are in the minority in every branch of state government.
