The reason there is more room for improvement in Republican political fortunes is that according to the Times, most survey respondents still don’t believe they’re getting a tax cut. In fact, almost all of them are. As this reality becomes manifest in paychecks this winter, there’s no reason to think the signature Republican legislative achievement of the 115th Congress won’t become even more popular.

As for the President who signed that legislation into law, ratings on a critical question are already on the rise. Mr. Trump remains underwater on the general question of his handling of the presidency, with a majority in virtually every poll expressing disapproval. But he is showing increasing strength on the issue of the economy, which just happens to be the issue that frequently decides elections.

This week, the Economist/YouGov survey shows him ten points above water, with 49% approving of his handling of the economy compared to only 39% who disapprove.
