Given these developments, the future of the Western world isn’t the only thing to be worried about. For several groups of people—the G.O.P., Wall Street, the super rich, etc.—the fate of tax reform, which was already facing serious obstacles, has been thrown further into question. Corker is a powerful Republican senator, and he was on the fence about supporting a bill that would add to the federal deficit even before the tweeter in chief trashed him. Because it’s unlikely Democrats will support legislation that would provide huge tax breaks for corporations and the wealthy while potentially raising taxes on the middle class, the G.O.P is hoping to pass tax reform through reconciliation. But, as the Times notes, Trump can only afford to lose the support of two Republican senators on the vote.

“The margin for error in the Senate is already perilously slim for tax reform and the president’s comments undoubtedly hurt that push,” Issac Boltansky, an analyst at Compass Point wrote in a note to clients Monday. Cowen Washington Research Group analyst Chris Krueger added: “Either Trump realizes that Corker can sink the remainder of the Trump/GOP legislative effort and is upset by that reality, or he didn’t/doesn’t know and just made it reality. Either way, we see ZERO upside for the budget process/tax reform in this Twitter-tantrum with the policy downside limit-down.”

Considering how much Trump is expected to personally benefit from the tax-reform plan proposed by the Big Six, you might think that, just for a second, he could conquer his impulse to act like an idiot online. But, as he’s proven time and again, you would think wrong.

Reminder: Trump’s DACA policy would actually hurt the economy

Fighting people on the Internet wasn’t the only thing on Trump’s agenda over the weekend. On Sunday, the administration sent Congress a list of demands for a deal to replace the Deferred Action for Childhood Arrivals (DACA) program it announced it would end over the summer. The list includes making it more difficult for unaccompanied minors to enter the U.S. illegally, cutting legal immigration, and approving money for Trump’s border wall. Team Trump claimed that “these priorities are essential to mitigate the legal and economic consequences of any grant of status to DACA recipients,” and that they “fulfill the president’s promise to advance immigration reform that puts the need of American workers first.” Shockingly, not a single administration official mentioned the study released earlier this year that estimated scrapping DACA would put a $433 billion dent in the U.S. G.D.P. over the next 10 years.

In related news, the Trump administration put out a press release today titled “What They Are Saying: Praise from the President’s Cabinet for the New Immigration Priorities,” in which people who literally report to the president talk about how great the president’s immigration plan is. The best quote comes from the administration’s favorite 19th century Robber Baron, Commerce Secretary Wilbur Ross, who wrote that the money Trump has requested to increase border security “will be money well spent!”

Trump inspires new generation of people with zero government experience to run for office

If this idiot can get elected, why can’t I? is apparently the thinking on Wall Street these days.
