text:  In just a few hours, we will be in the middle of the most highly anticipated event of the 2024 presidential campaign, the first debate between President Biden and former President Donald Trump. ABC national correspondent Stephen Portnoy has a preview. The face-off will take place in CNN's Atlanta studios. The two candidates will be just eight feet apart, standing at lecterns facing the two moderators. The debate will last 90 minutes, and the intent is for listeners and viewers to hear a substantive debate without distracting crosstalk.
