I know a (well known conservative/Liberterian) that worked on campaigns early in his career who is adamant that this Iowa Caucus debacle was deliberate by Washington in order to withhold the impact of a Bernie win, because they knew it would it have resulted with a lot of Press fanfare.
By trickling out the results over 3 days, it effectively diminished the important impact of a Bernie win in Iowa which would have resulted in him charging onto New Hampshire, likely taking it by storm.
He said the DNC don't want Bernie because they know during this crucial election year, with radical Bernie attached to it, they will lose the House and never regain the Senate.
He said Mikey B is their most desired choice, because one thing that boring Bloomberg has, is money. Petey B has no money and that's what the House and Senate elections need -- money.
Lots of it.
Example of how in he is, most election campaigns offices don't even have furniture, yet Bloomberg spent $350,000 on furniture alone. He has the money, he will spend it, he will throw it at his Party and that's what they need. The Dems don't care if they get the Presidency as much as they do the House and the Senate.
