Yes, and it's now just something new. There have been dozens of changes in just the past few weeks, and there is no commonality anymore from one state to the next.
Previously, there had been minor differences, but nothing that would keep the public from knowing who won by at least the day after election day. Now it will probably be weeks or months, unless it's a landslide. Even then, there will be plenty of disputed elections down the ballot and lots of court cases. It'll make Gore vs. Bush look like a piece of cake.
