I'll repeat the question: What is the best way to catch them? (My suggestion at the end)
My original interest in these threads really started in 2004 when I witnessed my wife at the adjacent DRE loudly complaining: "ALL I want to do is vote for Castor!" as the machine continued to change her vote to the repub. candidate. Even though the machine was "reset" by the poll worker "technician", it was clear that the election in Pinellas County Florida was hacked that day. The same voters who approved an increase in a school tax referendum and elected about 2/3rds Democratic local officials supposedly elected several national repubs by a close margin. Here's a paste from one of the earlier discussions:

http://us.share.geocities.com/electionmodel/TruthIsAllFAQResponse.htm#Election2000"M.1. What about the reports of flipped votes on touch screens in 2004?
Many people reported difficulty voting on electronic voting machines (DREs), in particular, that attempts to vote for one candidate initially registered as votes for another. The Election Incident Reporting System (EIRS), connected to the "OUR-VOTE" telephone hotline, recorded close to 100 such incidents. TruthIsAll has asserted that 86 out of 88 reports of electronic vote-flipping favored Bush. He cites the odds of this imbalance as 1 in 79,010,724,999,066,700,000,000. Another observer reports that actually, 87 out of 94 EIRS reports favored Bush. The odds of this imbalance are, of course, still prohibitive -- on the order of 500 trillion to 1 against.
Is this compelling evidence of a stolen election? No, it really isn't at all -- because the actual election returns from DREs on crucial states don't support election theft concentrated upon DREs. In Florida, some analysts who looked for evidence of vote-switching on DREs concluded that the optical-scan results were actually more suspicious. (Of course, it is possible that both could be hacked.)"
I still contend that the hacking of DRE's, compilers, and faulty source code is virtually impossible to detect.
I think that comprehensive exit polls at the PRECINCT level are still the best route to provide the overwhelming evidence to expose the hackers. In Florida, so many people are fed up with this after the last decade that a "fraud poll" that allowed people to revote and compare the results would likely result in a large exit poll participation percentage.
The exit poll that I envision would have to be convenient for voters, target early EIRS complaints, and clearly announce the intent to verify election integrity.
