Kyrsten Sinema, the Arizona senator who left the Democratic Party in 2022, announced that she will not seek re-election. This decision clears the field for a traditional Democrat vs. Republican matchup in the Senate race. Sinema's departure sets the stage for a showdown between Representative Ruben Gallego and the eventual Republican nominee, likely Kari Lake. Sinema's exit may impact the race, with differing opinions on which party will benefit. Sinema's departure effectively removes the last Democratic-aligned senator opposed to changing the filibuster rule. She expressed frustration with the state of American politics and emphasized her commitment to civility and compromise.
