Axelrod has developed a maddening filibustering technique. He makes a point while talking normally, then you sense he will need to take a breath at the end of this sentence, so it will be the host’s turn to talk.
But he tricks you because he saved enough breath to ad a comma rather than a period, and starts another point, then takes a breath mid sentence when you can’t interrupt him.
I’ve heard one or two liberal callers do this on the radio.
Exactly the guy is super slick and may be running the show for all we know.
