The theme from Ryan and Trump is that you cannot proceed with tax reform until you repeal and replace Obamacare. Supposedly, it is a process problem related to budget reconciliation.
The rest of the Trump agenda allegedly hangs on what happens to Obamacare. The question you should be asking is why has the GOP failed in the past 8 years to come up with a consensus plan on the alternative to Obamacare. It should have been ready to go. The Dems had their plan (Obamacare) ready when Obama took office. Of course, Obama had a 60 senator filibuster proof majority. The Reps must deal with the reality of having only 52 senators.
You are right.
I hate plan but you are right.
