The fraud margin is about 2 to 3 %. I doubt they can generate more than that. A 4% spread should beat them every time. They are not prepared in a lot of areas to create the 3% fraud needed. Some races will be close enough for the fraud to work but not that many.
“A 4% spread should beat them every time.”
On an average basis, you are correct. But there are key contests where the results are likely to be razor thin (Ohio for example).
The idea of having to overcome 4% fraud voting REALLY ticks me off.
This is why both Whitman and Florina are toast in Mexifornia. Both are trailing, or even. That's not enough to overcome the margin of fraud.
