What changes in Senate if Warnock wins the seat
If Warnock keeps his spot in the Senate, that means a 51-seat majority for Democrats after their other wins in the midterms, which would make governing much easier than the current 50-50 split.
That includes confirming judges -- one of the few things that can be done in the Senate with a simple majority. With a Supreme Court dominated by Republican-nominated justices, Democrats have been eager to fill the lower courts with more liberal justices. A 51-seat majority could allow Democrats to move judges through the Senate confirmation process even faster, leaving them with more floor time to work on even more nominees or on other pieces of legislation they want to bring to a vote.
When it comes to legislation, Democrats would have the upper hand moving any of their legislation out of committee and to the floor for a vote with a 51-seat Senate. It would also give Democrats more breathing room when it comes to passing legislation by curtailing the influence of a single dissenting senator.
Additionally, Democrats would have a bit more security if a Supreme Court vacancy should open in the next two years.
