Republican presidential nominee Donald Trump retook the lead over Democrat Kamala Harris in the battleground state of Pennsylvania on the strength of a new poll, according to the latest RealClearPolitics polling average updated Tuesday.
The state has gone back-and-forth since President Joe Biden dropped out of the race on July 21. Harris most recently had 0.2-point lead over Trump but that changed Tuesday, with the former president now leading by 0.2, a key momentum swing with 50 days to go.
The difference: A new InsiderAdvantage poll published Tuesday showing Trump with a 50% to 48% lead over Harris in Pennsylvania. Before that, Harris enjoyed a bump from a USA Today poll published Monday that showed her with a 3-point lead in the state.
Three other recent polls factored in by RCP have shown them locked in a tie.
Pennsylvania and its 19 electoral votes — down 1 from the 2020 election — could be the key to winning the election.
Trump led Harris by 4 points in Pennsylvania on July 24, three days after Biden dropped out, according to the RCP average. Harris earned a tie on Aug. 16 before taking her first lead on Aug. 30, by eight-tenths of a point. Harris had done no worse than a tie since until Tuesday, according to RCP.
According to RCP's national polling average, Harris leads Trump 49.3% to 47.3%.
