For people who either vote strictly democrat and/or the people who simply cannot stomach another 4 years of Trump, instead of looking at platforms/policies I think the bigger and more important picture is who has the better chance of actually defeating Trump in November.
And the more I look at things, Bloomberg seems to have the best chance...plus, like I said earlier, he "has the correct change".
Cities operate jails and the state or federal government operate prisons.
By the way, Giuliani brags that he started Stop and Frisk in New York City.
Trump advocated for Stop and Frisk when he ran for President.
