Notice this article is positioned to address "conservatives."
What can we do to get the conservatives who still call themselves #NeverTrump … to vote for Trump?
It is not addressing that class of leftist liberal democrats like Kasich, or Jebbie, or Romney, et al.
So with respect to that leftist liberal democrats, trying to have a normal conversation with them is like teaching pig to sing. Don't try it, it is a waste of time.
On the other hand, real "conservatives, such Mark Levin, have come around.
So therefore, you can tell a real conservative from a leftist liberal democrat. Real conservatives, such as Mark Levin, have come around; but the leftist liberal democrats - well, they haven't and they won't.
