Sanders also has been able to work well with his colleagues. He's passed bipartisan legislation and forged strong relationships with members of both parties in nearly 25 years on Capitol Hill. But most of all, members say, even when Sanders is ideologically an outlier, he lets others know where he stands. He's not the type to suddenly stab a colleague in the back. And that's earned him respect both on and off the Hill.

Sanders has also passed an amendment to the Dodd-Frank bill that led to the first audit of the Federal Reserve. He and Sen. Robert Menendez secured funding in the 2008 stimulus bill for clean-energy initiatives. And he inserted language into the Affordable Care Act to increase funding for community health centers.

But as with Coburn, Sanders' willingness to stand up and say no has also helped him to score victories on Capitol Hill. Sanders highlights his battles to prevent Republicans from cutting Social Security benefits as well as "the complete decimation of the U.S. Postal Service."

Last year when we had the scandal at the VA, he was incredibly effective, engaged in getting the legislation passed, in getting it funded. Frankly, without him, I don't think we would have gotten it done because there was a lot of name-calling but there wasn't a lot of constructive, 'OK, here's the resources. ...' And he did it," Reed said. "And it was a great testament to his skill as a legislator."

Sanders has a system, said Sen. Sherrod Brown, who served with him in the House before both were elected to the Senate in 2006. "He would call them 'tripartite amendments' because we'd have him and he'd get a Republican, he'd get a Democrat and he'd pass things. He's good at building coalitions," Brown said.

Just before Vermont Sen. Bernie Sanders excoriated Wisconsin governor Scott Walker’s record to a cheering crowd of 10,000 at a Madison arena on Wednesday night, Walker’s staff tweeted: “Thousands of veterans suffered in VA scandal yet @BernieSanders downplayed it & attacked those who exposed it.”
The tweet, to say the least, was misleading. The Vermont senator and self-described democratic socialist, now seeking the Democratic presidential nomination, has long supported our veterans—even if he doesn’t support all our wars. And in 2014 he accomplished the last thing you might expect from a candidate whose campaign brand is firebrand: He negotiated a major bipartisan agreement with two conservatives to deal with the veterans health care crisis.

From the moment the long-gathering scandal broke into public view in April 2014, it took Congress less than four months to produce a new law—a split second by Capitol Hill standards. That it happened at all, and so fast, was a testament to the determination of Sanders and his partners to surmount the red-blue divide in American politics. It speaks volumes in particular about Sanders, who pushes for a single-payer government health system in every speech, that the law introduced a private-care option for veterans.

But Sanders is not an ideologue in the mold of a Michele Bachmann or a Ron Paul, both of whom made far more headlines than laws during their years in the House. He is not averse to compromise or incremental progress, and he works within the system to make that happen. In January, for instance, he and Sen. Patty Murray were the lead writers of a letter asking Obama to update overtime standards in order to make more people eligible for overtime pay. Obama announced such an update a few days ago.
