I suspect the Iowa Caucus final results will show Bernie getting a little windfall at the end and winning. The trickled voting results show a steady rise by Bernie and I suspect they are simply doing all they can to reduce the "surprise" factor for Bernie.
Bingo! I just checked the results, Gay Pete has 26.2 percent, and Bernie has 26.1, with 97 percent of the vote in.
Bernie is going to win this thing. The Dem leadership could not have all the headlines, "BERNIE WINS IOWA." This is their nightmare since they believe a socialist can't win the Presidency.
The Dem leadership deliberately slowed down the announcement, this cushions the bad news for Biden, and cushions the good news for Bernie.
