With a debate and a second assassination attempt in the rearview mirror, the Harris-Trump contest is by any measure too close to call.

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.

In the last two elections, the victorious candidate won the support of Wisconsin by 0.7 percent margin both times.
