Senate races to watch in November

In a polarized, closely-divided Congress, the fight for U.S. Senate control comes with high stakes. This year’s elections will determine whether Republicans or Democrats capture a Senate majority, or if the present 50-50 split continues.

There are 35 Senate seats on the block this November, of which 21 are held by Republicans and 14 by Democrats. Seven incumbents aren’t running: six Republicans and one Democrat. 

Numerically, Republicans have greater exposure for loss, with more of their seats at risk. But the national winds are blowing against Democrats. That means Republicans may have the momentum to win the toughest fights.
