Oh, it's definitely both an indirect call for his more violent supporters to do things before the election, and a threat of what he will do after the election, though it's not really a threat they can avoid considering he's pretty much guaranteed to go after them either way, even if the majority of Jews suddenly decided to support him.
The wheel of bigotry always hits certain groups, and the Jews are one of them.
Part of me wonders if the reason he phrased it this way may have been on purpose, to signal to the antisemites that, if he gets elected, he will be hostile towards the Jews.
