Hillary Clinton's comments comparing the primaries in Florida and Michigan with the elections in Zimbabwe were half right. She was right that there is something wrong with changing the rules of an election when you don't like the result, but she was wrong to think that she is different from Robert Mugabe.
People went to the polls in Zimbabwe thinking that their votes would count. But then Mugabe saw that the results weren't what he wanted, so he changed the rules and the results didn't count.
In Florida and Michigan, people went to the polls thinking that their votes would not count. But then Clinton saw that the results weren't what she wanted nationally if Florida and Michigan didn't count, so she tried to change to the rules to make the results count.
