I couldn't find the figures for the city of Los Angeles, but considering it's substantially smaller and no more Democrat friendly then New York, it's inconceivable that trumps still doesn't lose the National popular vote by at least close to a million votes.
Some quick napkin calculations suggest that Clinton's PV margin in Los Angeles proper is somewhere between 700-800k votes.
You have a pretty good napkin!!!!
City of LA:
Clinton: 1,017,038 --- Trump: 212,080 Margin 804, 958
