You're right. Reagan's actions speak for Ronald Reagan. And the man who fired the insubordinate PATCO union slackers, wouldn't have allowed a county judge to deploy local police against a state agency and state law-enforcers. That's a rebellion, and Reagan wouldn't have stood for it.
PATCO does not apply here. That was a business issue that affected the national economy. Firing the Air Traffic controllers was a labor issue. There is nothing that you can show me that would indicate that it was an ultra vires action on the part of Reagan. The Shiavo case isn't that simple. Reagan had firm beliefs, but he also respected the office of the Presidency, the Constitution and the Rule of Law. He would not have thrown those principles out the window. Unless you can show me a case on point, don't say that Reagan would have done it.
