During the 2016 Republican primary campaign, Trump touted his dealmaking skills as a way to distance himself from what he called “crazy zealots,” like rival Texas Sen. Ted Cruz. “We’ve got to have somebody who’s going to stand up and make deals,” he told Cruz during a February debate.

As the campaign wore on, Trump explained away his decades of political donations to Democrats by telling voters, “No one knows the system better than me, which is why I alone can fix it.”

He also repeatedly dismissed and derided the work of former President Barack Obama’s diplomats and trade negotiators, suggesting he could have made much better deals than they did.

Whether or not Trump’s dealmaking abilities helped him collude with Russia to win the U.S. Election–and if they did that would be considered a hugely ‘successful’ deal–Trump’s success as President of the United States has been less-than-zero. Zero, because he has not passed any legislation in over 120 days, and less-than-zero, because he is under investigation by the FBI, the House, the Senate and a special prosecutor. In fact, Trump has been such a failure, his own lawyers are preparing for the possibility of impeachment.

What is so stunning about Trump’s fast fall is that so much of it can be attributed to Trump’s own mistakes in handling the situation and his ability to alienate just about everyone with whom he could make a ‘deal.’
