The current schedule lists two more debates: the last debate is not yet set but will occur in November. I will change the expiry time when that is set and it it is clear there will be no more debates by the end of the semester.
In the first debate, Trump participated in an interview with Tucker Carlson on X (twitter), and his picture from Fulton County Jail dominated the headlines, potentially taking media attention away from other GOP candidates. It is unclear if this media advantage will continue.
