They parrot their bullshit so often and so earnestly they come to believe it.

considering the varying interests at play. Recall how long it took to get ACA out?

a half years has been to do everything and anything they can to destroy the policies of Obama and obliterate the quality of life for the citizens who voted for a black president even if it means taking most Republicans down as well?

They want the checklist covered before 100 days is up, because they're winners, and if anything hasn't been marked up by the time 100 days is up, they're losers.
Republicans don't care if they pass real legislation or not, they just want anything to shove in front of their constituents to keep them happy.
It's all about the image, and saying the right things. It's never about what you actually do, because whatever you do...IOKIYAR.

how to "replace it" and know full well how horrible it is (see cut most of the revenue and deficit spend to keep it in place past their 2018 re elections before pulling the plug and having it blow up on everyone).

Just trying to bully it through.

Trump probably requested Mitch and Ryan to bring it up immediately, even if it isn't ready to go?

He will do anything to get the attention off himself. Especially when it is negative attention.

Russia connection blows up in their faces. To put as much space between it and the mid-term elections in the hopes people will forget who screwed them out of health insurance. And, most importantly, because they are ignorant, evil, little assholes.

How could they not demand we pass it immediately if it's the World's Greatest?

so they had to roll it out quickly

To figure out health care is complicated. Obviously they can't be expected to have a coherent plan that would improve on the current situation.
