First, that's Minnesota, not Pennsylvania, and different states have different electoral processes. Second, you had 113 people convicted of voter fraud out of 2,850,000 votes cast. That's about 0.004 % of the votes cast. Even if you take the largest claim of that article, that 2,800 votes were illegally cast, that's less that one tenth of one percent of the vote. To put it another way, if every single one of those votes had gone to John McCain, Barack Obama still would have won by over 295,000 votes. And that was the worst case of voter fraud in 75 years, which is hardly representative of overall levels of voter fraud either nationwide or in Pennsylvania where this law is in effect.
