Ryan could’ve said, “Mr. Vice President, I’m noticing that you never look at me when you’re talking.. What are you afraid of?”.. LOL
The key to winning a debate is, don’t concentrate TOO MUCH one what you’re going to say next! Stay in the NOW, listen to your opponent otherwise you’ll miss out on opportunities to counter punch!
Biden was playing to the theater of his mind. It is scary to imagine what he thinks of himself in there.
But yes, Ryan should have caught and held Biden’s eyes until Biden got the message, or as you say, challenged Slow Joe to make eye contact. Or he could have said, “When I think sentencing our children’s children children to penury is funny, I will let you know.” Just call sh!t for what it is as soon as possible.
