I think Trump knew exactly what he was doing. He knew this was Obamacare lite and that his base did not like it. I think he planned for this to get shot down because I believe he was wanted Obamacare to carry on long enough to completely go up in flames so the dems can be faulted. Ryan is now diminished and will hopefully find himself on the outside looking in. President Trump can now carry on with HIS idea of what Trumpcare should look like.
That's the part I really like.
