Why else is Bernie still in this then?
And she did steal a lot of delegates in states where Bernie won the popular vote. This definitely happened, more than once. And probably happened in the popular vote too given your elections are a joke with the rigged machines. Don't care to do the statistical analysis to prove it this go around, but it's happened just about every election since the electronic ballots were implemented in a statistically obvious way. Ballot flipping with Ron Paul in 2012. Kerry/Bush in 2004. And in 2008 there was more of the same during the Republican primaries.
You don't draw crowds like Bernie does and not win, at least not in a non rigged game going by traditional thought about expectations based on appearances in public (ie: number of signs, crowd sizes on appearance etc). But it's happening anyway.
