Underrated Biden advantage; Republican brain drain?

[Arizona Iced Tea]

It's a decent argument but wouldn't Dems have always had this advantage? Obama had big support among college educated voters, Gore/Kerry had an "intellectual" base against "low IQ" Republicans, and I doubt anyone ever wanted to work for Dole's DOA campaign. I think this is one of those things that's less of an advantage but more of a small detail that is baked in the cake already.
