Amy Walter:

That's right.

And, you know, the interesting thing about where the relationship is right now between Republicans in Congress and the president, this has been an on-again/off-again sort of relationship. A lot — for earlier in the year, a lot it was an off-again type of relationship, with the president taking to Twitter to criticize his own party, especially after the failure of Obamacare.

Now it's an on-again relationship with the passage of the tax bill. But where there still is work to be done now, Republicans have to get an on-again relationship with their own voters, especially congressional Republicans.

Remember, at the height of sort of discontent between the president and congressional Republicans and Republican leaders, Republican voters were saying they trusted President Trump more than Congress. They thought the leaders in Congress, Republican leaders, weren't doing enough fast enough. They were blaming them for stuff not getting done.

So, Mitch McConnell may want to get stuff done in 2018. The first thing you have to do is repair the relationship with the voters. And the second thing is to sell this tax bill. Remember, even among Republican voters, they may say they like it, but they're not as deeply in love with it and excited about it as some of the Republican members who voted for it, especially those who say that they voted for President Trump.

I was looking through polling about this. They voted for President Trump not simply because they liked him, but more because they disliked Hillary Clinton. They are less enthusiastic about this. And I think that it's the job of Republicans now to spend a lot of 2018 getting them excited about this legislation.
