I think the article reads waaaaay too much into the letter. It does not say that Perry supports what the task force ultimately decided to propose. It merely says that the idea of reforming health care is laudable. A lot of people agree with that (although admittedly I’m not one of them).
IMO the real point of the letter starts in the second paragraph: a request that special attention be paid to farmers and rural areas.
I have my doubts Perry initiated this by himself. That said, he is responsible for what goes out under his signature. But this does not convince me that he is insincere. Every politician has written letters like this one.
Those other politicians are not in the running for the top slot under the Republican label ~ nor will they be if it’s found out they supported Hillary-KKKare.
