It now takes a 2/3 majority to stop legislation the president wants rather than to pass legislation the president does not.
Many positions which normally require Senate confirmation no longer do. The president can just appoint an “acting” person in that position indefinitely, bypassing Senate confirmation altogether.
The president is no longer required to divest in his business interests.
The president is now allowed to practice nepotism unchecked.
It is now okay for the president and his family to personally benefit financially from his office. (Not that it wasn’t always “kind of” okay anyway, as Hunter Biden’s undeserved job in the Ukraine shows.)
It is now okay not only to allow foreign governments to interfere in our elections, not only to encourage it, but to actively seek interference from foreign governments, paying for it with taxpayer dollars.
The president can now order any person not to comply with Congressional subpoenas without consequence. The president, alone, decides who may and may not testify.
The president can now override Congress’s power of the purse any time he wants and for any reason, arbitrarily deciding to hold up or divert funds however he sees fit based on his own personal agenda.
The president can now override any law he does not like and is no longer required to perform his duties in pursuit of duly enacted Congressional laws. This one first appeared when Congress slapped more sanctions on Russia, I believe in year 1, and the President simply refused to enact them. It has been repeated multiple times, the last time when holding up funds to Ukraine.
The president can exact revenge any time he likes on any person who upsets him, even if there is no good cause, including arbitrary revocation of security clearances and firings.
The president’s personal properties may be used interchangeably with government properties, funneling taxpayer dollars into the personal property as the taxpayers foot the bill for Secret Service to stay in luxury accommodations at Mar-A-Lago and Trump Tower.
That’s just a short list of the serious things I can think of off the top of my head. I’m sure there are a lot more, and maybe even some more serious things (though several of those are pretty serious) that could be added. We really should keep a running list of the serious and dangerous ways in which our government has changed under the orange clown. Not just the things we don’t like or the things we think he did wrong, but the things which are actually fundamentally changing how our government works, all of which are taking power from the other 2 branches of government and giving them directly to the president. Added together I think democracy is taking a pretty serious hit. Of course pretty much none of these things will be okay again once a Democrat is in office. Then Republicans will break out the righteous indignation that the president would dare cost taxpayers money to go on vacation once in a while. Never mind the fact that most Democrats wouldn’t act this way.
