As did Ronald Reagan. What would you do? Exile all of them?
I just finished writing a reply to the wall Street Journal.
I'll shorten the substance since it addresses you as well.
It is a sign of desperation to invoke Reagan as a means of silencing, distracting, or minimizing conservatives' feelings on this issue and how it has been handled.
I take the fact you've done so as a sign you are desperate and fearful a split is happening right before your eyes that you cannot control.
