I felt that deep sense of confidence that comes with rigorous preparation. Like accepting the nomination, these debates were a first for me. The pressure you feel when you’re about to walk onstage is almost unbearable—almost, but not quite. You bear it by working hard to get ready. You bear it by having good people by your side. You bear it by not just hoping but knowing you can handle a lot, because you already have. At least, that’s what always worked for me.
