I haven't found much on him, but I found this:
They type him as ISFJ but idk why, they don't go into detail and just state quotes from or about him.
Prior to the campaign I'd never heard of him. It seems most people outside of Indiana haven't heard of him before either.
I've been watching some videos, and sat through the entire VP debate. He seems confident and pretty chill, not mad or worked up. Good at speaking too. I'm not good at typing, ideas?
