With S. 649 likely Senate Majority Leader Harry Reid’s last chance to pass gun control legislation in this session, Senator John Manchin (D-W.Va.) has been working hard to bring the National Rifle Association into the discussion on how to make the bill palatable to those opposed to the background-checks. On the other hand, Senator Rand Paul (R-Ky.) has been working on an effort to stop the legislation by filibustering it.

But Paul’s effort was thwarted on April 11 when the Senate invoked cloture by a 68-to-31 vote (8 more “yea” votes than needed to invoke cloture), allowing the bill to proceed. Shortly before the vote, Senators Paul, Mike Lee (R-UT), and Ted Cruz (R-TX) released a joint statement saying, “The effort to push through legislation that no one had read highlights one of the primary reasons we announced our intention to force a 60 vote threshold.”

The 68 senators who voted for allowing the anti-gun bill to proceed included 13 Republicans and 9 Democrats with “A” ratings with the NRA. The “A” rated Republicans who joined Democrats in voting to invoke cloture included Lamar Alexander (R-Tenn.); Kelly Ayotte (R-N.H.), Richard Burr (R-N.C.), Saxby Chambliss (R-Ga.), Tom Corburn (R-Okla.), Bob Corker (R-Tenn.), Jeff Flake (R-Ariz.), Lindsey Graham (R-S.C.), Dean Heller (R.-Nev.), John Hoeven (R-N.D.), Johnny Isakson (R-Ga.), Pat Toomey (R-Pa.) — and, with an “A+” NRA rating, Roger Wicker (R-Miss.)

Manchin had been working for weeks with the NRA to soften some of the language in the bill to make it more acceptable to his colleagues for when a vote is taken on the bill itself. With the help of lawmakers possessing “A” ratings from the NRA, the bill will now proceed to that up-and-down vote.

Ruby Cramer, who has been watching developments closely, reported at  that Manchin was banking on the NRA to go along with changes, giving enough political cover for pro-gun senators with A ratings from the NRA be able to vote for it without damaging their perceived support for gun rights. Cramer quoted Manchin’s communications manager, Jonathan Kott, as saying that Manchin “always talks to the NRA and has a great relationship with them, especially back in his state [of West Virginia]. Those lines of communication will always be open.”

After working with another allegedly pro-gun senator, Republican Pat Toomey from Pennsylvania, Manchin announced a “bipartisan compromise” on April 10 that could open the door for passage of the controversial measure. Said Manchin:

Today is the start of a healthy debate that must end with the Senate and House, hopefully, passing these commonsense measures and the president signing it into law.

The events of Newtown, truly the events at Newton, changed us all. It changed our country, our communities, our town and it changed our hearts and minds.

When he was asked about whether he was worried about his A rating with the NRA, Manchin replied, “What matters to me is doing the right thing. And I think [this bill] is the right thing.” He added:

We’re here for a purpose to do things. This is the right thing to do. I would hope that just having a score or a rating they would look at it and say, “Did we do the right thing? Did we use common sense? Did we do the right thing to protect lives, protect our children?” I would hope we would get credit for that. I can’t help the scoring system.
