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.

Cleveland Ohio had 100% Obama voting in 16 precincts, and more than 93% in at least 100 IIRC. The numbers still don't give Romney a victory, it's about 1200 votes to take from Obama's count and give to Romney. The high 90's votes for Obama are probably more correct than the 93% black exit polling, the latter is probably low since they didn't poll in those 100% Obama ghetto precincts.
As for turnout, generally 60-70% in Obama land, more than Romney territory in many cases.
