No, I've never done this
So even though Obama's Biden pick brought this old Life in Hell strip to mind, I have to say that it's pretty much applicable to whole heck of a lot of running-mate selections from both parties I can recall. When you think about it, the whole process is just laughable, and kinda reminds me of situations where a guy and girl absolutely despise one another but at the end of the day somehow end up in the sack together. But when a guy can't stand a girl, or vice versa, and they end up sleeping with one another, they invariably have friends who'll heap scorn upon them for such a bad decision. The difference between that and a presidential election is that after the awful choice is made, the next morning everyone is expected to forget all that history and say "wow, they make such a cute couple!"
