So they’ve agreed to two debates.
Friendly suggestion to the organizers: enforce time limits MERCILESSLY. Have an automatic timer on the mikes. Have a count-down clock in clear view of both candidates. The instant it expires, the mike gets cut. If it gets cut mid-syllable, so be it. Such are the consequences of failing to pay attention to the clock and running over.
Also, only one mike live at a time. A turn is a turn. No interrupting allowed. Want to refute something? Wait your turn.
