As it stands, Obamacare is set to start fully kicking in more fully in the next 2 years when most of the rest of the country starts to really experience the increased healthcare costs that only some (like myself) have felt since the start.
The GOP Bill being debated does not start to kick in for 2 years (after the 2018 elections) since they don't want to simply eliminate the Obama healthcare exchanges all at once and create a vacuum of coverage. Realistically, any change requires an implementation time (look at Obamacare itself which is 7 years in today & still not fully implemented).
The GOP would take the incessant blame for the rising healthcare costs over the next two years that were actually from Obamacare before the cuts would start to kick in thereafter, and the MSM would play that to the hilt for the Dems with the 2018 elections looming.
Today's vote is being obstructed by conservative GOP members who want Obama's "essential 10 healthcare coverages" repealed (a noble goal since so much of it is beyond what is absolutely required & we have the ability to pay for). But the problem Trump faces is that removing these coverages does not directly reference the budget and therefore is not immune to filibuster in the Senate by Reconciliation. In other words, to fully satisfy the freedom caucus in the House, Trump/Ryan would have to put up a bill that would need the old fashioned 60 vote majority in the Senate which they don't have.
But here is a potential play here (unless the GOP can find a way to appease the Freedom Caucus and still meet Harry Reid's Reconciliation loophole):
Satisfy the Freedom Caucus, let the House pass the bill & go to the senate. Let the Dems filibuster the Obamacare fix as the costs of insurance begin to skyrocket more, and let them pay the price for their own bill. This still would kick the can down the road toward the 2020 presidential election, but it would also allow time for greater congressional gains, and more flexibility in what reform could be implemented before then.
I don't think this is a preferable primary strategy, but should Trump not acquire the votes that he needs today for the bill in the form that he needs it to be in for the senate to pass, my guess is that this is the hand that he will likely play. This should be interesting.
