The fight for the Senate couldn’t be tighter. The chamber is 50-50 and the top Senate contests are as close as they can get. Republicans need to net one pickup to take control.

As the election nears, it is coming down to only half a dozen seats or less with really four that could provide the key — Pennsylvania, Georgia, Nevada and Arizona.

Pennsylvania is so important to Democrats, because if Lt. Gov. John Fetterman can hold on against celebrity TV doctor Mehmet Oz, then Republicans would need to win two of three of Georgia, Nevada and Arizona.
