A paper trail? Seems to me that the ballots in Florida--the ones with the hanging chads--were also a paper trail. Even with a "paper trail" through some other means, you're gonna have "whiney Dems" complaining about stray marks, half punches, and partial signatures. It's what they do best, when they don't win.
The Republicans trying to vote for Senator Rick Santorum, who saw the electronics switch their votes to his opponents, were right to file complaints about that.
