Trump is still trying to get his cabinet confirmed. As for ACA repeal/replace, anyone with common sense knew it'd be complicated. No surprises here.
Anyone with common sense knew shutting down Gitmo would be complicated.
Anybody with common sense realizes that Repub leaders are ideologically opposed to the kind of tax & redistribution efforts that have extended healthcare coverage to the 20M Americans under the ACA. That ideology extends to education & other aspects of the public good as well.
It's all about greed at the top, about people who don't need more more money or more power getting more of both. When they get done tinkering with healthcare, education, financial regulation & the rest it will be at the expense of the 99%.
Despite the tsunami of bullshit it's obvious that Trump believes in the same things if we look at what he's done his whole life rather than what he said recently.
