Experienced, knows how to get things done

Which candidate?

But in spite of persistent carping that Mr. Sanders is nothing but a quixotic crusader — during their first debate, Hillary Clinton cracked, “I’m a progressive, but I’m a progressive who likes to get things done” — he has often been an effective, albeit modest, legislator.

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.

“It has been a very successful strategy,” said Warren Gunnels, Mr. Sanders’s longtime policy adviser.
