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.

The state’s closely watched Senate race shows a similarly tight contest, and 93 percent of registered voters say they are certain to vote.

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.
