Jack Smith is going to resign his unconstitutional job as Special Counsel before Trump takes office and fires him. He will release a final hit on Trump with his Special Council Report where he will proclaim that Trump is guilty guilty guilty. Then he may write a book and take his place as a "legal expert " in the compliant press.

What is his record in high profile cases besides the Trump fiasco ?

I'm sure he has some success somewhere . I did not scour his body of work. He ironically once headed up the DOJ public integrity unit under the emperor. Under his watch the Russia hoax coup was engineered .

His high profile prosecutions ? 0 for all

He convicted former Guv of Va Bob McDonnell only to see SCOTUS unanimously reverse it.

“there is no doubt that this case is distasteful; it may be worse than that. But our concern is not with tawdry tales of Ferraris, Rolexes, and ball gowns. It is instead with the broader legal implications of the Government’s boundless interpretation of the federal bribery statute.” ....

Smith went after Dem former VP nominee John Edwards.Of the 6 counts Smith 5 were dismissed with a mistrial and one resulted in an acquittal .

The outcome of the six-week trial was a high-profile blow to the Justice Department’s beleaguered Public Integrity Section and a told-you-so moment for many in the legal community who ridiculed the case from its outset.John Edwards trial: How the prosecution stumbled - POLITICO (https://www.politico.com/story/2012/06/how-the-edwards-prosecution-stumbled-076942)

Smith went after one of the most corrupted Dem Senators ever Robert Menendez. This should've been a slam dunk..The case ended in mistrial
One juror told reporters that 10 of the 12 jurors supported finding Mr. Menendez, a Democrat, not guilty, saying that prosecutors had not made the case that the favors and gifts exchanged between the senator and a wealthy eye doctor went beyond what good friends do for each other.
Following the ruling, Mr. Menendez seemed both relieved and defiant, denouncing prosecutors who pursued criminal charges against him. “The way this case started was wrong, the way it was investigated was wrong, the way it was prosecuted was wrong, and the way it was tried was wrong as well,” he said.

Smith got a conviction against Arizona Rep Rick Renzi. Trump pardoned him.
Renzi has been adamant over the years that corrupt government agents launched the “Eagle Operation” to frame him and remove him from office.
In April 2020, an official complaint was filed on behalf of Renzi, according to Thomas Glessner, president of the National Institute of Family and Life Advocates, with supporting documents showing prosecutorial misconduct and illegal activity. The complaint sought a full investigation by the Department of Justice.

Upon his release Renzi said ;

“After almost fourteen years of fighting for my innocence, it took a real man of action and courage in President Trump to finally relieve me of the horrific deceit of being wrongly convicted by a Department of Justice that engaged in witness tampering, illegal wiretapping, and gross prosecutorial misconduct.
“Because I refused to plead guilty to a crime I did not commit, a prosecutor even resorted to suborning perjury in order to secure a fraudulent conviction.
“I went to prison and was wrongfully incarcerated rather than cower and plead to the DOJ fabricated narrative that I was guilty.

Jack Smith's misconduct over the years needs to be investigated . He can't be permitted to quietly exit and ride off into the sunset.

What is Trump NOT guilty of? Breaking the law? (hmmm, how many times?) Cheating on a spouse? (hmmm, how many times?) Grabbing females by the p---y? (hmmm, how many times?) Starting and saying he would lead an insurection that he ducked out of and watched on tv? (hmmm, only once so far) How many of his businesses have failed? (hmmm, count 'em!)

What's positive about the man? Do we really want this man leading our country? Leading us into what???

So many things to dissect in your comments.

breaking the law .... So far he has been convicted in NY and will have the charges reversed in appeal The charges against his were concocted by a corrupt DA and a judge who's daughter fund raises for his political rival .The charges were for an alleged crime where there was no victim. The banks he is supposed to have defrauded testified on his behalf ;and said that given the opportunity they would do business with him again. The prosecutor pasted together a hodge podge of local and campaign finance laws to build a case that has as many holes as a slab of swiss cheese. So that takes care of breaking the law

Cheating on a spouse. Since when is that a disqualifier for the Presidency. For that matter ;since when is having high moral character a prerequisite . We are not voting for a Pope. Do I have to detail all the moral slugs that the left consider great Presidents ? oh what the hell . Here is a partial list of slugs considered great Presidents by the left Woodrow Wilson ;FDR ;JFK ;LBJ ;Bubba

Starting and saying he would lead an insurection completely false. New evidence reveals that the Jan 6 investigate was every bit the Kangaroo Court that I said it was. They ignored the part of his address where he told those attending to protest peacefully . Turns out he wanted the National Guard deployed at the Capitol and the military ignored his instructions . Turns out Madam Mim Pelost intentionally neglected her responsibility to provide Capitol Security . Turns out there was hours of Capitol security we were not shown including Capitol police opening the doors and inviting protesters in, Turns out the only person who dies at the Capitol was Ashlee Babbit who was executed by a Capitol Police Lieutenant who was reckless in the handling of firearms .

I will concede that Trump allowing so much time between when the riot started and when he took to the media to try to cool it down was irresponsible and unPresidential .

Failed businesses. Plenty of businesspeople have had failure . Let's see if I can name a few .

Bill Gates ;Steve Jobs ;Thomas Edison ;Walt Disney ;Jeff Bezos;Richard Branson ;Fred (Colonel) Sanders ;Milton Hershey . I'd say Trump was in good company .

Failed businesses

“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.” -Teddy Roosevelt

But are any of those men our future president for the next four years?

Throw in Bill Clinton while you're at it, and he was a two-term pres. Also throw Hillary into the mix. I don't know of any bigger lie told than her accusations of Russian assistance to the Trump campaign. And that doesn't take into account her Kosovo whopper, and yet liberals flocked to the polls to vote for her.
