As I said again and again, trump is simply following the fascist playbook. You have to at least grant it to him, it is virtually the only thing he’s good at. Do you know which other very popular democratically elected leader skipped presidential debates a few years ago? It’s the guy waging war to Ukraine.
Headline is crap, he deflected the question by answering that he doesn’t believe Trump will be the nominee. Sure he hasn’t “ruled it out”, but any other response would imply he thinks Trump will win.
