Over one 12-year stretch in the House, he passed more amendments by roll call vote than any other member of Congress. In the Senate, he secured money for dairy farmers and community health centers, blocked banks from hiring foreign workers and reined in the Federal Reserve, all through measures attached to larger bills....
Mr. Sanders has done much of his work with Republican partners, generally people with whom he has almost nothing in common, with the notable exception of the discrete issue or two on which they see eye to eye.
He 
worked with Senator Charles E. Grassley, Republican of Iowa, to prevent foreign workers from replacing Americans at banks that have had a federal bailout, and with former Representative Ron Paul of Texas, who shared his zeal for monitoring the Federal Reserve.
Mr. Sanders’s most notable partnership with a Republican was also one of his greatest successes. In 2014, Mr. Sanders, as chairman of the Senate Veterans Affairs Committee, worked out an accord with Senator John McCain, Republican of Arizona, on 
a bill to expand veterans’ access to health care after a scandal involving veterans’ hospitals across the country.
The bill did something Republicans wanted: It allowed veterans to go outside of the official hospital system to get care under certain circumstances, while it expanded the government services that Mr. Sanders demanded.
“Given how liberal he is, it made the work hard,” Mr. McCain recalled last week. “But he was an honest liberal. I’ve worked with people who tell you they are going to do one thing and then do another, and Bernie did what he said. And he was very effective. It was the first real reform of the V.A. ever.”
