I think the broadcasters in particular were terrified of "getting it wrong" like last time and so kept thier heads very well down on exit polls etc. It would still be very interesting to compare exit polls with recorded votes, and to compare for skewness between the different types of voting machines, as the possibility of vote rigging was never properly investigated in 2004 and may still be there.

IMHO one of the first things that the USA needs to clean up is its electoral and legislative system: -

Properly trackable votes
Properly trackable election funding
"Clean money" laws on election funding
Do something (not sure what) about lobbying corruption
End the abuse of tacking unconnected things onto the ends of other bills and hiding them so they slip through without scrutiny in late night committee sitting
Clean up the appointment of judges in general and supreme court judges in particular (the party political voting by supreme court judges on the "hanging chad" and other 2004 election issues would have disgraced a banana republic)
Separation of church and state
Multiculturalism in education

And where has the press been on all of these?
