... but not this time. Eugene has been a consistent advocate of the idea that people should not make too much of politicians minor gaffes when speaking without a script. He has rightly pointed out that everyone makes mistakes and/or is sometimes less than clear when speaking.
Sometimes though, I think he takes this kind of thing a bit far.
As I've long said, these sorts of errors (here about what medium presidents were using to speak to the public in 1929, and even about exactly who was president in 1929) are inevitable when people speak extemporaneously, especially when they're in the middle of a hectic campaign and probably not getting much sleep. All this shows about Senator Biden is that he makes errors just like all the rest of us. But it's worth remembering incidents such as this one when people start mocking other candidates for similar slip-ups.
I'm all for giving people a great deal of leeway when speaking, but if the fact that Biden stated publicly that Roosevelt was President during the stock market crash of 1929 and was making televised speeches years before TV was a viable communication tool doesn't say anything about him other than that he's human, what kind of mistake would Eugene allow as revealing?
