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.

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

A poll released Wednesday by Quinnipiac University, meanwhile, is closer to the Inquirer/Times/Siena findings, suggesting Harris is leading in Pennsylvania by 6 points, 51% to 45%. The same poll found Harris leading in Michigan 50% to 45% and in Wisconsin by 48% to 47%.

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

A new poll of Pennsylvania shows Vice President Kamala Harris and former President Donald Trump remain locked in a close presidential race, while Dave McCormick is gaining ground against Bob Casey
