I don’t think he should keep his mouth shut.
Again, you can't have it both ways. No bueno. And you can't cherry pick and tell Trump what to say or what not to say. You can always vote for H. Clinton if what Trump says does not meet your approval. Simple.
I reject your framing of the argument - “You can’t have it both ways... You can’t cherry pick...”
Of course I can choose to comment on certain aspects of Trump’s approach, and leave others behind.
As far as voting for “H. Clinton,” only brain-dead liberals, fools, gibsmedats and traitors would do that.
