What can be learned fro the Iowa Caucus Fiasco?

What can be learned form the Iowa Caucus fiasco? There are few things. First, and foremost, the democrats cannot be trusted to run universal healthcare and all the other freebies they want to offer if they cannot run an election. Second, I am not sure if the results of the election can be trusted. There have been more strange happenings in the DNC and about the Iowa Caucuses. The DNC recently changed the rules for debates so Bloomberg can get on the debate stage. Why? They want to stop Bernie and there are more rumors the DNC may change the rules of super delegates back to those that favored Clinton in 2016 (Clinton earned over 95% of all super delegates). This, again, is a fail safe to stop Bernie. On the eve of the Iowa Caucus the Des Moines Register refused to publish the results of their poll. The Register said they had an inconsistency in pollsters conducting the survey. Maybe, but with more and more polls favoring Bernie it looks like bias could have also been the reason for their change of heart of publishing the survey. Since most people in the state read the Des Moines Register, they did not want to influence more people to get on board the frontrunner bandwagon. Maybe everything is on the up and up, but there are a lot of fishy things going on and lets not forget how the DNC colluded with the Clinton campaign so she would beat out Sanders for the 2016 nomination. Not only was the super delegate system rigged, CNN and other debate hosts were supplying Clinton the questions before the debate. The hacked DNC server showed their bias towards Clinton. If the DNC did not want Sanders in 2016, I doubt he is their first choice out of 20 candidates in 2020. It just seems fishy. Maybe the results show Sanders wins, but that does not mean results are not being altered to some degree.
