But if Republicans’ unenthusiastic responses on Wednesday are any indication, Schumer will probably have to put the bill on the floor in order to find out if it can pass. Senators like Burr, Romney, Ernst and Young aren’t giving hard “nos” by any means, but they aren’t racing to provide the 10 ironclad commitments Democrats would need to make same-sex marriage a law, either.

Even retiring senators were keeping their views to themselves about the four-page bill. Burr (R-N.C.) merely said: “I haven’t looked at the legislation. Is that too much to ask for?”

“I’m aware of this bill. I haven’t looked at it,” said Sen. Pat Toomey (R-Pa.), who many Democrats think is open to voting for the same-sex marriage bill and backed a nondiscrimination bill in 2013…

But other than a handful of hard nos from the likes of Sens. John Cornyn (R-Texas) and Lindsey Graham (R-S.C.), most Republicans refused to tip their hands. Sen. Chuck Grassley (R-Iowa) said he’s waiting for his staff to review the legislation, Sen. Ron Johnson (R-Wis.) said he needed to review it and Sen. Mike Braun (R-Ind.) said he’s not commenting on it yet.

“I haven’t given consideration to that legislation in part because the law isn’t changing and there’s no indication it will. And clearly the legislation from the House is unnecessary,” said Romney (R-Utah).
