He said, "Next time vote for someone who is well-educated so you don’t have to go through this again." I agree with him, and moreover I think teachers should be allowed to express themselves because everything is political. But I can't in good conscience argue that this was a politically-neutral statement. In particular, the words "Next time" are saying very plainly that he doesn't think it went well this time. This is a political argument against the current ruling government.
