Nonsense. He's not the legislature. And he's the one that got concessions that Ryan didn't want to give.
It's not even close who is more to blame for the debacle, except for the predictable anti-Trump crowd.
The Speaker of the House is the one who introduced this bill. It was authored and rolled out under his supervision. He's the leading legislator in the House. The President gave him a chance and the Speaker blew it.
Nope, a new president has his greatest legislative powers at the start of his term—and he most effectively uses them by presenting a bill to Congress and then lobbying both the reps in Congress and the American people to get it passed.
Trump largely ceded that power and authority to Ryan and the RINO leadership in Congress. Now he is using that failure as an excuse to work with the Democrats at the expense of the conservatives.
