Trump didn't break any new crockery which, given his record for the first four weeks of stepping from one steaming pile into the next without letup, was a major accomplishment. Of course, someone else wrote those words, not Trump, so we'll have to watch which of the various pronouncements he steps on over the course of the next week. Trump has a knack for contradicting every position which he establishes, which is why the whiff of chaos is ever present.
Trump moved slightly back toward center, which he'll have to continue to do if he wants to have develop a working majority that can pass legislation. In that he was wise. Divisiveness can only take you so far.
The Dems applauded on breaking the lock on drug prices, and infrastructure development, but I'd be surprised if either of those are high on Trump's list. I don't expect the infrastructure idea to ever actually get implemented. I think the patter which will emerge is Trump's wealthy buddies get the goodies, and Trump's working class followers will get the excuses ("Well...we just couldn't find the money for that, what with the tax cuts for business, and the tax breaks for the wealthy).

I'm sticking with my position; Obamacare is going to squeak by and survive because Congressional Republicans like their jobs, and have been watching how the town halls have been playing out.
At some point somebody is going to remember that health care costs were already spiraling out of control BEFORE Obamacare, and they aren't likely to stop increasing faster than the rate of inflation even if Republicans are able to kick a few million people off of insurance. Obamacare didn't fix all of the problems with health care, but it was a good start.
If Republicans do manage to crater Obamacare, not only will they own the problem for ever after, but it their approach fails -- there's nothing left but single payer. Which, frankly, is the only really sane option.
