Didn't stop Taft.
That was a long time ago. Whole different world.
He was elected almost 100 years ago (1908). Long before TV or radio and the need for a presidential candidate to be attractive, if not always glib. Fat men were viewed as 'substantial' in those days and a trim build in middle-age usually meant poverty, which indicated that you were either stupid or just plain lazy.
That was then, this is now.
