She lives in her own reality and isn't affected by external events. She surrounds herself w/people based on how long they've known each other, how much they agree and how much she trusts them.
Case in point - this is the 2nd primary night where she was thoroughly trounced in multiple primaries, and she DOESN'T EVEN ACKNOWLEDGE that a huge loss, or even a primary, just took place, much less who won it. She's too busy IGNORING REALITY to get her message across to the voters in the next state who are surely a bit confused as to what to think and are looking to her for guidance to interpret the results. I don't think anyone expects her to concede the nomination or otherwise complain or belabor the facts, but ACKNOLWEDGING them is a MUST.
I haven't seen ANY OTHER candidate on either side deliver a rally speech after just finding out they lost BADLY that didn't start with congratulating the winning candidate, or at least mentioning that they didn't get the results they were hoping for. I find it offensive and a sign that Hillary is just not accepting of the people's will that they don't want her. I also worry it's a sign that her win at all costs mentality is going to lead to a scorched earth policy where she'll go all out negative and fight tooth and nail to get all the super and even Obama-pledged delegates to get her the magic number despite the will of the people.
It's still not over and no one expects her to drop out now (although that might be the best for the party and nation), but they DO expect her to realize that she has in fact lost the last TEN STATES and quite badly. Completely ignoring those facts makes me worry about what other facts and realities she refuses to accept because they go against her version. We've seen this movie before and it wasn't and isn't pretty...
