Key Races and Factors Shaping the Fight for Congress

The battle for control of Congress is closely contested, with both parties needing only a few seats to flip the House or Senate. Key factors include ticket-splitting voters, the impact of the presidential race on down-ballot contests, and major campaign issues like the economy and abortion. Democrats have a financial advantage in campaign spending, but Republicans are leveraging outside groups to compete. Surprises may occur in unexpected races, such as in Nebraska and Texas, where Democrats are challenging Republican incumbents.
