United States Senate elections, 1964

His Democratic Party picked up a net two seats from the Republicans. As of 2016, this is the last time either party has had a two-thirds majority in the Senate, which would have hypothetically allowed the Senate Democrats to override a veto, impeach and remove certain officials, or invoke cloture without any votes from Republicans. The Senate election coincided with Democratic gains in the House in the same year.
