As Democrats debate how and whether to use power if they regain control of Congress and the White House, former President Barack Obama has lambasted his party for failing to more aggressively challenge or circumvent obstructions to enacting their campaign promises.

“There’s been some unwillingness on the part of Democrats in the past to break down some of the institutional barriers for us getting stuff done, just because, well, it’s always been done that way,” he lamented to a YouTube host earlier this year.

Obama said he was frustrated during his presidency with Senate filibuster rules, which require sixty votes to pass most legislation. He suggested it was a mistake for Democrats to preserve the filibuster “when it blocks us from making government effective,” arguing that it “makes people feel like government is corrupt.”
