McCormick overtook Casey with about 80% of the estimated votes counted just before midnight on Tuesday. Casey initially had a lead over McCormick when just about 40% of the estimated votes had been counted, propelled in part by mailed ballots that have historically favored Democrats. McCormick was doing better in votes cast on Election Day.
CANDIDATES: Casey (D) vs. McCormick (R) and three others
WINNER: Too early to call.
POLL CLOSING TIME: 8 p.m. ET Tuesday
ABOUT THE RACE: Casey hails from a well-known political family in the state. The son of a popular two-term governor, he served in statewide elected office as auditor general and treasurer before being elected to the Senate in 2006. McCormick is a West Point grad, Army veteran and former investment firm CEO who lost the GOP primary to Mehmet Oz in 2022. Sharp exchanges have punctuated the contest.
McCormick has accused Casey of being weak and a career politician. Casey called McCormick a wealthy, carpetbagging ex-hedge fund CEO. Pennsylvania Democrats have found success against GOP rivals in the recent Senate and governor's races.
John Fetterman beat Oz in 2022 by 5 points, and Gov. Josh Shapiro defeated Doug Mastriano handily that year as well, becoming the first governor to be elected to succeed a member of his party since 1966.
WHY AP HASN'T CALLED THE RACE: Casey still has a narrow path to victory.
