That's pure observer bias. The dems had enthusiastic crowds.
But the reports of districts going 99 or 100% for Obama tend to support this hypothesis
There's some evidence of fraud in 100% votes. However making then all 93% (the black exit poll result for Obama) would not change the outcome.
There are no observers that are not biased, including yourself. The crowds that I saw looked beaten. It was written all over their faces. If you saw some enthusiastic crowds, show me the footage along with the dates, not that it matters.
Making the 100% districts 93% in New York would not change the outcome, because that is a hard-core blue state, and if it was fraud, it was overkill, but 100% doesn’t happen except in banana republics. What I would like to know is if there were similar suspicious districts in swing states, with either excessive turnout or near-unanimous voting or both. There voter fraud would be outcome-determinative.
