In most ways, President Biden and former President Donald Trump couldn’t be more different. But they have one thing in common: frustration at the Senate’s filibuster rule, which has blocked both of their big-ticket initiatives from passing even though their party controlled the White House, House, and Senate.

For Democrats, the script is flipped from the Trump administration’s early days four years ago. Biden is unable to push through his proposed $1.9 trillion COVID-19 aid bill, along with a series of environmental plans and other legislative proposals, because Democrats cannot overcome the Senate’s 60-vote requirement for ending debate.
