If I were in their shoes, Matt Gaetz and Rudy Guiliani,

Who stopped the Rudy investigation, Barr, or the former guy?

Why? Does Rudy have a lots of incriminating tapes on others? I think he will have, like Cohen made for insurance. Rudy will talk.

Reporters need to ask the former guy ASAP,

Did you have anything to do with the Rudy investigation getting stopped by Bill Barr. He has to lie or admit the truth.

What will the former guy do now?

He may accuse President Biden is corruptly abusing his power (which is what he and Barr did obstructing the Rudy investigation) , then call for with his minions his impeachment. He usually accuses others of his crimes.

We'll know very soon the other guy is scared of Rudy,

He'll start projecting , and have others projecting Rudy can't be trusted, and is a drunk, and how he was fired because he's crazy, and start bad accusations against him, which is all lies. He'll start a distancing campaign, and projection he worked on his own, and not for him. That'll expose his pattern of doing this to others, and a tell the former guy is guilty, and he's lying.

Will Rudy flip on the former guy and Barr and others?

Should Rudy be scared now because he knows too much, and they know he may flip on them to save himself? Will he be indicted very soon? I think those he has information on should be very scared now, especially the former guy and Barr. I think the former guy and Barr will not be sleeping good now.
Hope they have people watching over Rudy protecting him from being silenced by them. Rudy should know he's in deep, deep trouble now, from both sides, and he doesn't trust the former guy. He's knows how dangerous a position he is in now. Will Rudy be silenced like Epstein was? Wouldn't shock me if he was. Maxwell also could be in a similar position. They know too much.

What needs to happen now with corruption and election manipulation ,

An independent group forming a commission go after everything concerning election crimes. Especially people and groups conspiring to undermine our elections, and holding them accountable criminally. That means investigating dark money, foreign money, and criminal influence , and raising money illegally. Manipulation of an elections results, the companies behind doing this corruptly, and the money people helping finance this, or it'll get worse and be used even more to undermine our Democracy.
Politicians taking money from foreign countries especially need to be exposed, and face serious consequences, and all tactics used to refuse to count votes, like signature rejections. The politicians need to not have any seats on this commission, and non-partisan people well respected for it is key to keep them from engaging in obstructing it. We have to restore law and order in politics, and our elections while we can , or we will lose . Those behind election fraud need to be accountable, and have consequences.

There should be laws preventing any vote from being rejected for signature differences,

Without having proof of who signed it, and signed statements the real voter did not sign it. There has to be a record in each state of any ballot rejected because of this , or like with other issues it becomes corrupted, and people illegally use it for political reasons for their vote tally's. Disabled people like me can't sign their name the same, so this is a stealing of our votes, if this happens. Is there ways in every state people can check to see if their vote was counted?
Is there a record of all voter ballots rejected kept? Is this just another heavily used tactic to not count votes when the race is close? Any lawsuits from this happening? How would anyone know if this happened to them by the fascists party, formerly the GOP. No ballot should get rejected without documentation, and proof its not from the actual voter. Not from someone claiming by looking at it and saying it doesn't count. People rejecting votes without documentation, and evidence should have severe penalties and consequences for doing this. Every state needs to have set up a system for voters to check their vote was counted and who for, and a record of it that can easily be checked.

How long now before the former guy will claim the verdict was corrupt, unjust, and unfair?

While getting his white supremacy party to promote whites are the victims . He also sometimes suggest certain people are his targets for this happening, like rep. Waters. His people in Congress will be told to spread his propaganda , like he's done with the big lie, and many other issues. He will try to use this to divide people with , using his standard propaganda to stay in the spotlight, I think. He'll also use it as a distraction from his bad news as it's exposed.

If the former president was still in office now,

He would be moving mountains to have stopped this trial of Chauvin already with threats, installed extreme loyalists and racist's to undermine any accountability for the murder of George Floyd, and incited his extremists groups against anyone protesting for this now. Moscow Mitch wouldn't be saying anything against it either. The GOP are now a racists domestic terrorist group , corrupt, and serial liars welcoming these groups into their party, and by the former president, and promoting more gun violence. Justice has to be returned in this trial, and restored for our country and Democracy to survive, or these fascists win, and we turn into putins russia.
