Modern elections are interesting because they're so close. I believe they're so close because polling has become nearly a science and the funding on both sides allow a professional process. That means small mistakes or single bad performances decide elections in a way they couldn't even 10 years ago. It's interesting, even for outside observers like me (limey brit)
