AMY WALTER, The Cook Political Report:

Well, I think Tam summed it up pretty well. The fact they only spent 18 days on something is issue number one.

The second is, of course, that two-thirds of the members in the House right now who are Republicans have never been with a Republican president, so this is a brand-new situation for them.

And these divisions, I would argue, within the Republican Party have been around longer than the last couple of years. They have been around for 10 or 12 years. So, this is a lot to overcome.

I think the other thing we learned, though, was that Donald Trump's style, which worked on the campaign trail, the let's just rally and take one for the team, I can bring the team together in a campaign, didn't work in a legislative sense. It's not enough to just say, hey, members of my own party, vote for something that's really unpopular. I can't really talk to you about the details of this policy. I'm not ideologically attached to this piece of legislation. I can't even tell you that I want to spend a whole lot of time selling this legislation, but vote for it because you like me.

And what his party said was, that's not enough. It's a really important factor as we go forward to whatever the next piece of legislation that this Congress wants to get through. The power of persuasion of this president isn't enough, even though he remains popular among his own base.
