You realize that gerrymandering had zero impact on the Presidential race?
The rules of the electoral college were well known in advance and Hillary and crew insisted beforehand that everyone should pledge to accept the results of the election. They insisted they had an electoral lock because of the Big Blue Wall in the Midwest. She was so confident she didn’t campaign in Wisconsin. Bad move. Complaints after the fact just shows she is a sore loser. Is the system the best system possible? Probably not, but as Hillary explained to Bernie’s supporters she was better at rigging the system than he was so she deserved the nomination.
