The doom/gloom tactics are old.
Very subjective commentary and the inevitable Hitler reference for a President who didn't start any wars and welcomed diversity.
Presidents replace staff all the time. It's not really a measure. Some replace more some less.
The question that needs to be asked is why was he elected last time and why does it look like he'll be elected again?
Hmmmm. Those are good questions. I can answer them fairly broadly. But the main reason is Fox News and the right-wing media echo chamber.
In 2016 (and for many years before the election), Hillary Clinton was vilified on Fox. She was to blame for Benghazi (despite 12 investigations, including congressional hearings that showed she did nothing wrong), she was dragged through the mud for the private server situation, and of course Fox and the right-wing media actively helped Trump. He got free airtime to rant and rave about whatever he wanted, and there was never any pushback on his lies. They provided cover for all of his scandals, from the Access Hollywood tape to allegations of sexual assault and other affairs. You had the opinion folks provide advice and spin to help with strategy and cover. In any other election, Trump would have been destroyed or would have dropped out of the race.
And let's not forget that James Comey broke DOJ regulations by announcing they re-opened the server investigation in late October, only to say it was again closed just before the election. That was certainly election interference, because most legal scholars said it could have/should have been done quietly, especially when there was a strong chance that nothing would have come of it.
Another thing to consider is that America became even more divisive during the Obama years, thanks to the right-wing media. Let's not forget what this outrage factory pushed. Obama had the gaul to wear a tan suit!!! Obama is not American, he's a muslim from Kenya....the list goes on and on. The whole birther situation and the growth of the Tea Party had serious racial undertones. Tea Party extremist eventually morphed into MAGA supporters, and Trump knew how to blow that dog whistle so they were attracted to him.
Now, I'm not going to say all MAGA are racist, but it does seem to be a fact that most racists and bigots support MAGA. These people buy into the lies that there is some master plan to stop America from being a white majority. They believe those lies about caravans and massive illegal immigration (I mean, that is a problem, but by objective measures, it is massively exaggerated). They think climate change is a hoax and buy into the "Soros" influence. They also start to distrust the mainstream media because they report objectively and don't blow things out of proportion. This is acutely seen during the COVID pandemic.
Fast-forward to today. Many of those things have become even more hyper-partisan. There is a growing apathy in politics. Biden is old. Trump ain't much younger, but still lies about virtually everything. The economy has issues. There is still inflation, but Biden has guided the US to the lowest levels of unemployment in like 50 years. Wages have grown, manufacturing jobs are returning at a greater pace than what Trump saw. Violent crime, after spiking during the pandemic, is falling. But, if you only watched Fox or Newsmax...you wouldn't know that.
There are many other reasons for his victory in 2016 and why he could win again. But I think Fox gets a lot of the blame. Let's also remember that Roger Ailes created the idea of Fox after Nixon was forced to resign. He basically said that a media outlet that was right-wing could defend the indefensible. And, that's what Fox became. It is nearly an extension of the RNC/GOP. Say what you will about the biases and leanings of MSNBC or CNN, they are nowhere close to being as aligned with the Democrat party as Fox is with the GOP.
