It is forecast that the $1.3 trillion estimated cost of annual foregone revenue from Trump's tax reduction plans (out of a total revenue intake of $6.3 trillion annually) is a shortfall of 20.1% which would be offset by $5.9% increase in revenue from Trump's tariff plan.
In sum, a total loss of $14.2% of federal revenue with no plans for how to make up the shortfall. He has suggested giving the President control over the Fed to set interest rates as well as control of the money supply (printing money). He has also suggested to eliminate the debt ceiling. Economists & the Congressional Budget Office have derided both of these ideas as leading to precipitous rises and consumer prices and dangerously inflationary.

More detailed breakdown:
Donald Trump's proposed tariffs to make up this revenue loss from his tax cuts (which include a 10% worldwide tariff and a 60% tariff on Chinese goods paid for by the American consumer - so in effect a hidden tax), are estimated to generate approximately $280 billion annually.
If the 2017 Tax Cuts and Jobs Act Trump legislations provisions are made permanent, it is estimated that the federal government would experience a reduction in revenues of approximately $400 billion annually.
Additionally, the long-term fiscal impact would increase the national debt by $16.5 trillion over the next 75 years. This revenue loss primarily arises from the continuation of foregone income tax introduced by the TCJA.
Regarding the image above, Trump has NO ability to influence insurance rates as they are set at the state level, Congress has signaled that they have no plans to restore the state and local tax deduction (SALT), the president has no ability to mandate coverage of IVF treatment and the president has no ability to set credit card interest rates.

Trump demanded that Republicans shut down the government unless the continuing resolution contained a measure requiring proof of citizenship to register to vote. It is already illegal for noncitizens to vote in federal elections, and the measure was widely seen as an attempt to suppress voting. Trump was unable to command Republican loyalty on this issue as he did earlier this year when he insisted Republicans kill the bipartisan border bill.

That recognition of his slipping power might have been behind his hastily announced press conference this afternoon at Trump Tower in New York, a press conference best described as the September 10 presidential debate 2.0.

Trump reiterated his vision of the United States as a hellscape. He insisted that the nation’s booming economy is actually hemorrhaging jobs, that the FBI statistics showing crime falling are all lies, and that inflation, which has fallen close enough to the target of 2% that the Fed recently began to lower interest rates, is at an all-time high.

Trump reserved his greatest rage for the ABC debate moderators who, he complained, fact-checked him after agreeing not to—“I want an apology,” he said—and for Democratic presidential nominee Kamala Harris. To her he attributed what he insists is a flood of undocumented immigrants drowning states in a welter of crime, although we know immigrants commit crimes at a lower rate than native born Americans. He recounted in some detail a number of horrific rapes he claimed were committed by immigrants. He did so apparently with no self-consciousness about his own liability for sexual assault that the presiding judge said would commonly be understood as rape, although his focus on rape could have been an attempt to push back on the the recent spate of ads by conservative lawyer George Conway’s Anti-Psychopath PAC featuring woman who claim Trump sexually assaulted them.

Are these signs of obvious desperation the beginning of the end for trump?

"In particular, there's evidence that the car seat rules that we've imposed, which of course I want kids to drive in car seats, have driven down the number of babies born in this country by over 100,000. So as we think about how to make kids safe here, I think we should do it in a way that's accommodating to American families."

When there's a school shooting, the right says we need to stop making school gun free zones where only authorized people can have guns, so since someone was killed at a Trump rally, shouldn't he have had the chance to defend himself?
