While Jeb Bush (and others) have promised new and better voting machines, the last I heard was that the money they promised had vanished and wasn't going to be around. But they were trying to go to a Touch Screen system. (I have suspicions about such a system though - I think it would be more prone to tampering.)

As for the Chad issue - two things

1. There have been complaints about the punch system in prior elections. (However those races were decidedly won and it was ignored.)
   
2. One state has apparently found problems with the punch system and their legislature actually requires them to count dimpled chads. (So it's not just Florida.)
   

Ah well, Florida - we can't get the voting thing worked out....but we can teach terrorists to fly into buildings!
