I don't think Bloomberg has a chance, because he was a Republican and then he switched to the Democrats.
However, he shouldn't keep apologizing for his "stop and frisk" policy, it's enough of political correctness. If there's a lot of violent crime in a "minority neighborhood" the police should be able to check on people. It sounds bad but the alternative is leaving them to kill each other with impunity. I know it is disproportionate, but is the only way.
