Independent voters are a must-win for both Harris and Trump in the swing states, where polls are currently very close.

Pennsylvania Sen. Bob Casey (D) is leading his Republican rival Dave McCormick in new Keystone State polling. In a new poll from The Philadelphia Inquirer/The New York Times/Siena College, Casey garnered 49 percent support from the likely electorate in Pennsylvania compared to McCormick’s 40 percent.

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.

Three new polls show Pennsylvania Democratic Sen. Bob Casey’s lead over GOP challenger Dave McCormick narrowing — with one finding the candidates separated by just 1 point. A joint New York Times, Philadelphia Inquirer and Siena College poll shows Casey (48%) leading McCormick (39%) by 9 points among registered voters — with 13% still undecided.

The race for U.S. Senate in Pennsylvania remains tight between incumbent U.S. Senator Bob Casey (D) and Republican Dave McCormick. A new Emerson College Polling/The Hill shows Casey with a 5% lead in the race with 47% support to McCormick’s 42%.
