"It doesn't matter who gets the most votes in an election; it only matters who counts the votes." - Joseph Stalin
In this election, there were reports of electronic voting machines that were changing the votes from Romney to Obama, while the Romney voters were casting their votes. It would only take 2-3% of the votes being changed, to entirely change the outcome of this election.
Therefore:
Investigate the electronic voting machines that were used in the 2012 elections.
How many electronic voting machines were used in the swing states, and where?
Who programmed them and where?
Carefully investigate the programs in them, and what they were doing.
