Bernie supporters need to stop banking on California for the following reasons:
1. Latinos adore the Clintons, have since the 90s
2. Despite being a true blue state, you still have many registered Democrats that wouldn't be far left or even conservative compared to the rest. My county (80% minority on the one hand, but wanted to uphold Prop 8 on the other) is a shining example of that.
3. It's one of the last to vote

4. The youth is well the youth and tweets aren't votes
Maaaybe if Bernie has a good day he can keep his gap below double digits, but I'd bet money on Hillary taking my state.
