It's very hard to make the votes disappear altogether because at the very least every clerk and every judge is keeping a running count throughout the day in addition to the count that the machine registers. Also, as part of the GOTV effort, there are poll watchers and poll runners who're keeping lists of exactly who has come in to vote. If the machine tally did not agree with the hand tally, or if the final tally did not agree with what was recorded by the Secretary of State, red flags would go up immediately.
The missing votes could have been changed to 0bama votes by hacking the machines I guess, but the problem is, you then still have very low turnout numbers (the total of them + us isn't changeable.)
The fact that Romney's people have not issued any court challenges tells me that the people on their rolls for GOTV pretty much agree with the counts recorded by the Secretary of State in the various states. So, the only real possibility is Republican votes were changed. But, if so, 0bama's numbers would have to actually be down by at least 13,000,000. That doesn't seem very realistic to me.
I'm really just completely baffled by these turnout numbers...
Here is another reason Romney’s count was down, insanity rules. Precisely because he was a Morman, and they saw no difference in the two. So they vowed to write in JESUS, but they ended up getting the Devil. Over 2 million votes.
