This brings up something I've never understood. Why did Bush Sr. pick Quayle in the first place as his running mate?

Forever debated among political scientists whether running mates win or cost their ticket elections, Quayle is a good example for the argument that they're perhaps overrated in their impact. Considering he was considered a joke from the get-go (if reading the opinions back then are accurate), and of course humiliated in the most famous VP debate moment in history, yet Bush Sr. still went on to whoop some Dukakis ass that year.
