My prediction is somehow he gets off with minor punishment.
If the legal waters get too hot for Donald I would expect Trump to cut a deal, or deals to save his ass.
And any deal if allowed would include banning Trump from serving as president ever again. A requirement Trump would have to agree to.
For Trump to cut a deal would be the admittance of guilt minus the punishment. Never holding office ever again in any government capacity would be the punishment as far as punishment goes. It will be interesting to see if Donald Trump would be willing to accept that requirement in order to avoid jail.
And knowing Donald Trump, Trump could just invent a new all-mighty position of leadership for himself. Like he did after the twitter ban when he simply invented his own media platform. Trump could invent his own position of high authority where followers would terminate their allegiance to the United States and swear allegiance to the authority of Donald Trump. As if Donald Trump were a government in himself.
Trump would make the laws, set the rules, set the guidance and collect the taxes while his followers quit paying the taxes and quit following the laws and quit following the rules set by the US government. All that would be left for the followers of Trump to do is to figure out where the hell they are going to live under this leadership of Donald Trump. Or instead, with all of those guns they own, Trump's people could just invade some state or maybe two and take over that land.
I guess we'll see....
