Vice President Kamala Harris will make a final pitch to voters Wednesday night at a CNN town hall in Chester Township, Pennsylvania, less than two weeks before the election and with early voting already underway.

The event, which begins at 9 p.m. ET, comes on the day CNN proposed a second debate between Harris and former President Donald Trump, which Harris accepted but Trump rejected.

Toward the end of the race, Harris escalated her attacks on Trump's basic mental competency, increasingly calling the former president incoherent and “unfit to be president of the United States.” She has also focused more sharply on his role in eliminating federal abortion rights, calling his often callous discussion of the issue a sign of “cruelty.”

Trump, for his part, has continued to speak out strongly against Harris and in recent weeks has seen fit to question — and sometimes attack — Jewish, black and Latino voters who support the Democrat.

But for all the rhetoric, organizing and hundreds of millions of dollars spent on campaign ads, the race looks like a coin toss – as both campaigns show signs of frustration with the relative stability of polls at the national and contested levels.

Here are five things to watch for during Harris' town hall, moderated by CNN's Anderson Cooper:

Trump talk: Harris' campaign team has increasingly questioned in recent weeks whether Trump is mentally and physically fit to serve another four years in the White House.

“It's becoming more and more unstable and unhinged, and it requires that response,” Harris told reporters in Detroit last weekend. “I think the American people deserve better than someone who actually appears to be unstable.”

It's in many ways a reversal of the strategy Trump and his Republican allies used for years to denounce President Joe Biden before the 81-year-old incumbent dropped out of the 2024 race in July. Harris, who just turned 60, has maintained a hectic campaign schedule and mocked Trump for skipping scheduled interviews – with one report citing “exhaustion” as the reason. She also seemed more willing to point out bizarre behavior, like when the 78-year-old Republican stopped a recent town hall to sway and sway for 39 minutes in front of a confused-looking Kristi Noem, the governor of South Dakota, who was scheduled to moderate dance the event.

At the same time, polls of undecided voters continue to signal that they want to know more about Harris and her political plans. She has already proposed one of the most ambitious expansions of senior care in modern U.S. history, though it is rarely heard in depth.

Harris doesn't necessarily have to choose to self-promote or mock Trump, but civic issues often give candidates leeway to steer the conversation. Where she goes will provide new insight into how she and her campaign view the race.
