If Arizona Democrat Mark Kelly wins a seat in the U.S. Senate, he could take office as early as November 30. Kelly has maintained a consistent polling lead over Republican Sen. Martha McSally, who was appointed to the seat held by the late John McCain.
Because the contest is a special election to finish McCain’s term, the winner could be sworn in as soon as the results are officially certified. Other winners in the November election won’t take office until January. A Kelly victory would shrink the Republican party's Senate majority at a crucial moment and complicate the path to confirmation for President Donald Trump’s Supreme Court nominee.
McSally has expressed that the current U.S. Senate "should vote on President Trump’s next nominee for the U.S. Supreme Court," she tweeted on Friday, shortly after Supreme Court Justice Ruth Bader Ginsburg's death.
