Even if there were not some sort of fraud to prevent a single Romney vote out of 400 and these ghetto blacks were allowed to vote freely, how many of them would vote for Romney? 4% or 16 out of 400 like the rest of the blacks? Probably less. A handful of votes out of 400 is probably the right number for that population. Getting zero in a few percent of the precincts may be luck or some voter coaching or an gang agreement or something like that.
Does it really matter that Romney got zero instead of the 4 that he should have gotten? Practically speaking, it does not.
Only problem with your logic is that in the precincts where Obama gets 400 votes and Romney ZERO! Were there really 400 legitimate voters there? Or are some fraudsters voting for dead or fictitious people via absentee ballot or early voting? With early voting a scamster can vote a few times if there is no photo ID requirement
It doesn't but I would love to see a statistician look at cities with a critical eye.
How many precincts votes at 50%, 60&, 70% or 80% of the registered voters? Too high a % indicates that fraud of bulk voting is in effect, especially in states with massive early voting.
What is the comparison of registered voters to the latest census estimates? Any more precincts voting 120% of the population?
What is the age distribution of voters in a precinct? A precinct that has thousands of voters over 80 y.o. is an anomaly.
What is the percentage of voters to the census estimate of voters (residents less illegals and prisoners)?
One that I would love to see - many precincts across the country consist of a single high rise building. What has changed over the years?
Some states publish a list of the people who voted - not how they voted but the fact that they voted in a primary or another election. What can be discovered about college student voting patterns? Especially CO and WA - beacons of vote fraud this year.
