“how does he circumvent the mute button?”
Completely ignores the questions of the moderator. Says what he wants to say about any subject he wants to, and asks Biden questions about Hunter for 2 minutes and then stops talking.
Rinse. Repeat for the entire “debate”.
huh ? Moderator says “off-topic” and mutes him. now what ?
That, and every time Joe lies, hold up a sign that says “Joe’s Lying!” When the “moderator” asks Joe a softball question, have another sign handy that says “Another softball”.
