Trump seems bent on political self-harm

Is President Donald Trump bent on political self-harm? It often seems that way. His overall job approval rating still hovers within a point or two of the 50% popular vote he received last November. But he is losing support on the economy and inflation, the No. 1 issue last year, while his overwhelming success in reducing illegal immigration has reduced the salience of what was the No. 2 issue.

Meanwhile, he is taking positions that a critical majority of voters consider simple lunacy. A prime example is tariffs.
