Summary
The Republican Dave McCormick won the Senate race in the battleground state of Pennsylvania on Thursday. Despite the call from the Associated Press, Casey has refused to concede the race.
McCormick’s victory means Republicans have now secured at least 53 seats in the Senate. Two Senate races in Nevada and Arizona remained too close to call as of Thursday evening.
McCormick’s win will give the party even more leverage to enact Trump’S agenda when the new Congress is seated in January.
