Ed Yardeni of Yardeni Research says President Trump’s protectionism is cause for concern:
"Too bad that Trump is starting to stir up a hornets’ nest over trade. That man just doesn’t know when to stop. He seems to have a compulsive tendency to snatch defeat from the jaws of victory. He could have done a couple of victory laps on getting Congress to enact a major tax reform plan that slashes tax rates for corporations and lots of individual taxpayers. The economy is booming and was likely to continue to do so through the mid-term elections, which might have allowed the Republicans to hang onto their majorities in the House and the Senate. Yet he is risking all that by pandering to protectionists. There really aren’t that many of them to pander to, so perhaps he is pandering to his own protectionist instincts."
