Because a teleprompter would be too obvious. [Updated] Biden Reportedly Refusing to Allow Search for Electronic Earpiece Before Debate
I would have someone set up with jamming technology, though technically it is illegal to interfere with a radio transmission, such interference can result from all kinds of things. Or you could monitor and record all the transmissions. I’m sure that they will be interesting. Though spread spectrum can make both difficult to do.
On Tuesday morning the Trump campaign requested a new rule for the first presidential debate: that a third party inspect both candidates for electronic devices or transmitters. President Trump had already consented to such an inspection, and the Biden campaign had reportedly agreed to this days ago, but Ebony Bowden of the New York Post reported moments ago that they are now declining.
Because they don’t believe he can get through the debate on his own.
Maybe Donald Trump should be debating Kamala Harris. (Hat tip to The Other McCain.)
