text:  From ABC News, I'm Richard Cantu. Thursday night's the night, the first Biden-Trump debate. New polling out of Quinnipiac. This new poll shows Donald Trump, though, with a slight lead up four points nationally. Now, the Biden campaign is well aware of this, and they see the debate really as a chance to break through to those critical, undecided voters who may not have fully engaged in this race yet and make clear to them the stark choice.
