On October 30, 2026, Elon Musk tweeted an argument for voting Republican, warning that a Democratic clean sweep of the House, Senate and White House in 2028 would end the filibuster and open the door to immigration changes and court stacking. He argued Republicans must hold the Senate now because only a third of seats turn over each cycle, and said 51 Republican senators in 2029 is all that prevents a permanent one-party state. Discussion has moved to what a sweep would bring, with Isaacson saying it would likely prompt retaliatory investigations.
