These three races will determine balance of power in the Senate: Klein
Senate races in Georgia, Nevada and Pennsylvania will determine which party controls the chamber next year, according to ABC News Political Director Rick Klein.
Whoever wins the two of those three are probably going to win the whole Senate,” Klein said as the first race projections started to come in from across the country.
The best chance for Democrats to pick up a seat is in Pennsylvania, Klein said, where Democrat John Fetterman faces celebrity Dr. Mehmet Oz.

"In Nevada, that's probably going to be Republicans’ best chance,” Klein said. “They see Sen. Catherine Cortez Masto as the most vulnerable Democrat anywhere on the map."
Here’s what to expect if Republicans retake majority control in the Senate.
