> Democrats could change the Senate rules to a simple majority with the support of all 50 Senate Democrats as well as Vice President Kamala Harris via the “nuclear option,” or a unilateral rules change.
The rules have been changed by a majority three times since 2013, once by Democrats and twice by Republicans — first on gutting the filibuster on most nominations, then on Supreme Court picks and finally to shorten the debate time for some nominees. Changing the legislative filibuster would effectively make the Senate much more like the House, a majoritarian institution.
