Trump has way more votes than Hillary in Arizona so far. So that blue/purple we wanted may not happen in that state.
Primary turnout usually has nothing to do with General election turnout. I still don't think AZ will be purple anytime soon but using these early numbers aren't the best source to make assumptions
Hillary is a safe bet for November, but we don't even know who'll be her rival. Logically it should be Trump, but until he's handed the nomination I won't take it as granted
