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.

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.

Although it could simply reflect the normal variation of polling results, it may also point to a declining Trump edge in the Electoral College.
