Harris’ entrance into the race has not reversed a larger trend of GOP party-registration gains, which leave Democrats in Pennsylvania with the smallest registration edge they have had in the quarter-century the state has tracked such numbers.

Given the recent polls and the collapse of the lead he once held over President Joe Biden, any path Donald Trump has to the White House must go through Pennsylvania — generally acknowledged as the most important swing state. Pennsylvania’s 19 electoral votes are the most among the seven top swing states.

Vice President Kamala Harris and former President Donald Trump remain deadlocked less than seven weeks before the Nov. 5 U.S. presidential election, according to new polls released on Thursday that also show a tight race in the key state of Pennsylvania.
