Not that I've heard.
He' s been remarkably supportive.
Even his endorsement of the props was marginalized by Tom's fair weather supporters.
As for the suporters, I know what you mean. I would have liked to have seen people be more supportive, but some seem more inclined to commit political suicide than help someone they don't like do something that was worthy.
As for Tom being mostly supportive, I think he tried to walk a fine line. His criticisms would sound like sour grapes if wasn't careful. I think he's tried to rise above that and not carp when he probably should have more often than he did.
Yes he has ... since the party endorsed him for state wide office.
Prior to that point he was candid in his appraisal of the Austrian's policies. Dozen of examples are contained in our archives. What is absent from his public pronouncements is any personal criticism of the Austrian, to McClintock's credit.
