He may have said he’s not “supporting” Trump, but I think he means he’s not supporting every position Trump is running on. I don’t think he’s said he’s not ENDORSING Trump. Like you say, he said he’s voting for Trump over Hillary. I’m pretty sure that’s the definition of endorsing in an election.
I don’t think he’s said he’s not ENDORSING Trump.
Yes Levin has said he is not endorsing Trump and he just said it again a little while ago.
