Delegates are not quite the same as votes. Pete is showing surprising skill at navigating the collection process.
Also Sanders has not won enough more votes to have any meaningful distance. And with such a small sample size of delegates it doesn't mean much
Iowa delegates are apportioned at county level. Pete won 60 counties, Bernie won 18, Pete ended up with 1 more delegate than Bernie. imo it’s about finding a nominee more likely to win electoral college than a plurality of popular vote. (I’m for Amy.)
We should get rid of the delegate game and the entire electoral college - it should be based on # of votes, period. If it were, HRC would be going into her 2nd term soon!
