I would add that -- despite the relative quiescence at the polls -- the Republicans need to re-write voter laws to remove the distinct possibility of future frauds. Register at the court-house at least a month in advance, no provisional ballots, no motor-votor, clear guidelins for poll-watchers & challengers, etc.
If this had been a bit closer, Kerry and his 10,000 DNC lawyers would now be making Gore's 2000 challenge seem quaint (disgusting though that was ...).
I think this is a priority. Much of election law is governed by the states, but I'd be very much in favor of a federal standard for federal elections, if possible. Something like standard ID requirements would help, even involving a voter ID card for which proof of residency and citizenship are involved (although I think most people would get hysterical at such a suggestion).
Residency requirements should also be standardized, and work should be put into developing a central voter database for federal elections, to eliminate the possibility of voters roaming the country voting in multiple places. I know that probably happened a lot in Florida, although fortunately it didn't do them any good!
I worked in the polling place, and I was impressed by the professionalism of our precinct supervisor, but it was unnecessarily difficult to identify the voters and make sure they were in the right place and were legally entitled to vote. Even banks conduct their business electronically, and having little old ladies poring over looseleaf notebooks in this day and age seems a bit ridiculous. So I'd also be in favor of infrastructure investments, such as having polling places have wireless data access to the databases, for example.
I would also add that all voter rolls are to be purged. Every American who wishes to vote must re-register. This is to be repeated every ten years.
