DAVID MUIR: Good evening tonight from Philadelphia. We are here at the National Constitution Center where tomorrow night, ABC News will host the first presidential debate between Vice President Kamala Harris and former President Donald Trump. The stakes could not be higher, with a new poll just out tonight, showing this race is tied at 49-49. The candidates will meet face-to-face for the first time on this stage with no audience in the room, a very intimate setting. They've never met before. It will be Trump's seventh presidential debate. It will be the first presidential debate for Harris. The Vice President arriving here in Philadelphia a short time ago after spending days in Pittsburgh in debate prep, complete with mock debates and stage lighting. In a new interview that aired today, the Vice President saying former President Trump is, quote, “not burdened by telling the truth”. The former president holding a rally in Wisconsin over the weekend, then meeting with his team, informally, he says, at Mar-a-Lago. But our team learning tonight he is preparing for this debate. Tonight here, the new numbers, where this race stands and the battlegrounds too.
