How so hasnt he wont the last 4 out of 5 states and is about to take California? And she won Kentucky by .5%...idk
She has had more voters vote for her than Sanders has. Around 3 million more. As a result she has won more votes where it counts and as a result has a delegate lead of around 200. And he would need to take California by 30ish% to surpass her in delegates. Assuming she doesn't win NJ or another state in June before the CA primary.
