Donald Trump's

Donald Trump’s mounting reversals, failures and betrayals make it increasingly clear that he is a fake and a fraud.

For many of us, this is affirmative reinforcement; for others, it is devastating revelation.

But it is those who believed — and cast supportive ballots — who should feel most cheated and also most contrite. You placed your faith in a phony. His promises are crashing to earth like a fleet of paper airplanes.

He oversold what he could deliver because he had no idea what would be required to deliver it, nor did he care. He told you what you wanted to hear so that he could get what he wanted to have. He played you for fools.

That wall will not be paid for by Mexico, if in fact it is ever built. If it is built, it will likely look nothing like what Trump said it would look like. His repeal and replace of Obamacare flopped. That failure endangers his ability to deliver on major tax reform and massive infrastructure spending. China is no longer in danger of being labeled a currency manipulator. The administration is now sending signals that ripping up the Iran nuclear deal isn’t a sure bet.

Trump has done a complete about-face on the Federal Reserve chairwoman, Janet Yellen, and when was the last time you heard him threaten to lock up Hillary Clinton?

This is by no means an exhaustive list of the positions he took for in-the-moment advantage that have been quickly converted into in-reality abandonment.

He isn’t cunningly unpredictable; he’s tragically unprepared and dangerously unprincipled.

“President Donald Trump’s image among Americans as someone who keeps his promises has faded in the first two months of his presidency, falling from 62 percent in February to 45 percent. The public is also less likely to see him as a ‘strong and decisive leader,’ as someone who ‘can bring about the changes this country needs’ or as ‘honest and trustworthy.’”

While the largest decline in the percentage of those who think Trump keeps his promises came among women, young people and Democrats, the number also dropped 11 percentage points among Republicans and nine percentage points among conservatives.
