Obamacare alone is no small accomplishment, given how many red state Dems she successfully corralled to vote for it. Same goes for the Iran deal after she lost her status as majority leader. There's a reason she's one of the most hated figures on the right, she's damn good at her job. Oh, and Filibusters don't take place in the House. They had a filibuster proof majority in the Senate for a hot minute, but that has nothing to do with Pelosi.
