Jeb might be the dumb brother
Oh he definitely is. I'm sure he has more book smarts, that's why he's hailed as "intellectual", but Jeb's problem is that daddy and everyone else pat Jebby on the back as the good boy, where as George W. had to learn lessons the hard way because he was the naughty boy. The fact is, George W. has more practical and personable knowledge than Jebby has so it's not even comparable which is the smarter of the two.
Dubya is the smart Bush brother. Chew on that for a moment.
