In Season Six of "The West Wing," the Democratic candidate selects an older, weathered politician with Washington credibility and loads of foreign policy experience (along with a checkered past and a slight hint of masochism to his personality), to counteract accusations of his own naiveté. Meanwhile, the Republican goes against the longstanding expectations of his party and selects a young, rising-star governor from a lightly populated backwoods state to be his running mate. While his candidate's main object is to help shore up the base, his VP choice immediate goes on the offensive against the opposition as their dedicated hatchet man. In particular, the VP's eye-opener of a speech at the RNC raises the ire of the Democrats, before the Presidential candidate gives a less partisan, "I promise to work for the American people" speech to close the event.
So really, the similarities between the show and real life seem to have disappeared, eh?
By the way, has anyone else noticed that Obama's tax plan is the one Aaron Sorkin proposed in Season 4? They're even defending it in the same way.
