When Trump said, “nobody knew” replacing Obamacare “could be so complicated”, did he mean YOU didn't know, or HE didn't know?

Ha ha do you think the Trumpet is finally admitting he's not perfect? Nah that couldn't be! But yes it's a sure sign HE got it wrong, HE didn't know!

He didn't know.  Anyone else with an iota of common sense would know how difficult such an endeavor would be.

Trump Is like a bull in a china shop. He says he is going to make all these changes without looking at the cost or what steps to take to make the changes.
He does not know what he is doing and just runs his mouth.

I think he's genuinely shocked that he can't just make things happen at the stroke of a pen.

Think about it.  He has no experience in government at all!  And I doubt he has much experience having to work as a team member with those that oppose him.

When easily  said platitudes run head first into reality...

not sure why theyd want to get rid of it, they should just keep it
