HARRISBURG, Pa. — Should former President Donald Trump debate Vice President Kamala Harris, now that she's the presumptive Democratic nominee for president?

That's what I asked Trump fans as they rallied for him Wednesday in Harrisburg, capital of swing-state Pennsylvania. Everyone I spoke to wanted to see Trump take on Harris. They were certain he'd come out a winner, even as they echoed his everlasting claims of unfair treatment.
