"If you wait until the last minute to figure out whom to vote for; if you can't tell the differences between the parties and their candidates (and you're not politically exotic — i.e., an anarchist or a libertarian); if you think voting is like a Chinese menu where you can pick a little from here and a little from there; then the odds are you don't know very much about the political system. You may be a brilliant neurosurgeon, but I know interns who are sharper than you about politics."
He makes a striking point. A lot of my friends have said they were big McCain fans, but have changed their minds recently for a laundry list of reasons I cannot even begin to comprehend. These are two candidates with dramatically different world views. If you are suddenly switching sides and going over to the "The One", it means you've had a life changing epiphany - like a life-long Muslim becoming a Catholic. If a Muslim were to become a Christian, it would mean he came to a realization that all the cherished beliefs he held all his life were wrong. A devout Muslim wouldn't convert because he thinks the local parish priest is "cool" and he believes his Mullah just doesn't seem to be "feeling" the Koran lately. Sadly, it seems some believe that it's just that easy. If that's the case, then you just don't get it and have a simpleton's understanding of politics.
