I would argue that the substantial regulatory reforms he is already phasing in, the substantial tax reforms he is now introducing in congress, and the pledge he has made to get better trade deals for American business and labour have already given some impetus to the market.

In turn, business confidence in this POTUS compared with its lack of confidence in the previous one has helped to give the US economy its 1st consecutive 2 quarters of 3% growth since 2008.   

But to return to the actual point of my post, the political case for and against Trump was litigated over 18 months in 2015 and 2016.

And the hang him high hoards within the media, Washington, Hollyweird and academia establishments should have the democratic decency to wait until the 2020 election campaign to manically re-litigate the political case for and against Trump. 

Meanwhile, the US would do well to let him get on with the things he promised the people he would do.
