According to Sanders' campaign manager Jeff Weaver, Sanders’ reason for opposing the Brady bill was two-fold. First, he believed implementing a national waiting period was federal overreach. And second, he was doing his job.

"He wasn't opposed to states having (waiting periods) if they wanted to. The Republicans wanted to repeal waiting periods in states that had them, and Bernie voted that down," Weaver said. "He said he would be against waiting periods, and he kept his word to the people of Vermont."

In April 1991, Sanders’ then-chief of staff Anthony Pollina echoed the idea that Sanders was simply representing the will of his constituents.

"Bernie’s response is that he doesn’t just represent liberals and progressives. He was sent to Washington to present all of Vermont," Pollina said. "It’s not inappropriate for a congressman to support a majority position, particularly on something Vermonters have been very clear about."

The Green Mountain State, though left-leaning, has a high gun ownership rate and lax gun control laws (as well as a low homicide rate). That and Sanders’ own personal views are reflected in his overall voting record, experts told us.

WASHINGTON, April 17 – Sen. Bernie Sanders (I-Vt.) today voted for expanded background checks on gun buyers and for a ban on assault weapons but the Senate rejected those central planks of legislation inspired by the shootings of 20 first-grade students and six teachers in Newtown, Conn.

“Nobody believes that gun control by itself is going to end the horrors we have seen in Newtown, Conn., Aurora, Colo., Blacksburg, Va., Tucson, Ariz. and other American communities,” Sanders said. “There is a growing consensus, however, in Vermont and across America that we have got to do as much as we can to end the cold-blooded, mass murders of innocent people. I believe very strongly that we also have got to address the mental health crisis in our country and make certain that help is available for people who may be a danger to themselves and others,” Sanders added.

The amendment on expanded background checks needed 60 votes to pass but only 54 senators voted for it. “To my mind it makes common sense to keep these weapons out of the hands of people with criminal records or mental health histories,” Sanders said.

Under current federal law, background checks are not performed for tens of thousands of sales – up to 40 percent of all gun transfers – at gun shows or over the Internet. The amendment would have required background checks for all gun sales in commercial settings regardless of whether the seller is a licensed dealer. The compromise proposal would have exempted sales between “family, friends, and neighbors.”

In a separate roll call, the Senate rejected a proposal to ban assault weapons and high-capacity magazines. That proposal was defeated by a vote of 60 to 40.
