Overall gay marriage support in the Senate: with map!

Who cares about people who say they support civil unions? Bush said he supported it in 2004. The current pope said he supported it. Last refuge of the bigots.

Republicans:
2 3 Supporters (Portman, Kirk, Murkowski)
41 40 Opponents
2 Ambiguous (Collins, the new R Senator in New Jersey -- but the Governor is not a homophobe and the appointee will be up for re-election in November 2013)

Jeff Chiesa is a place-holder and the state GOP has already ceded the 2013 special election.

Well, it is much easier to get the Democrat type of Republican than an honest Republican elected in NJ.

The only Democratic senators who have not publicly voiced their support (or, have said they support it but would not vote in favour of it) are Pryor, Landrieu and Manchin.

Yep.

Landrieu said she is personally in favor, but that she wouldn't vote in favor
Pryor has best tried to avoid the issue
Manchin just hates the gays
