We know that the national results could be tipped by manipulating the vote count in a relatively small number of jurisdictions a few dozen spread across a few key states. We know that the vast majority of local elections officials have limited resources to detect or defend against cyberattacks. And while pre-election polls have large uncertainties, they were consistently off. And various aspects of the preliminary results, such as a high rate of undervotes for president, have aroused suspicion.
Computers counted the vast majority of the 130 million votes cast in this year's election. Even without hacking, mistakes are inevitable. Computers cant divine voter intent perfectly; computers can be misconfigured; and software can have bugs.
Did human error, computer glitches, hacking, or other problems change the outcome? While there is, as yet, no compelling evidence, the news about hacking and deliberate interference makes it worth finding out.
About 25% of voters used machines that do not generate a paper trail. Any hacking, glitches or other errors that affected their votes could be undetectable. But the other 75% of the vote, including the key states of Michigan and Wisconsin, could be double-checked in various ways.
