Stumbled onto this little clip here, and it really stuck in my head. Obviously, it's pitch-perfect for current times, but it's interesting to watch the self-control that FDR could muster. Watch his hands tremble as he touches his nose, but how he keeps the grinning jauntiness going, just short of smug but not hitting it. He looks every inch the confident leader.
Also funny how scathing folks could be with the sarcasm back then. Politics has never been for the thin-skinned.
