Depending whom you ask, some will tell you that the New York City prosecutor simply pushed the case forward in hopes to break the ice so the most damaging cases can come after it. Trump is not actually scared of what could happen in the NY case, since it is difficult to prove he directed his former lawyer to do the crime.
On the other hand, the Georgia prosecutors have Trump in a record pressuring the state athorities to find votes for him and using subtle threats against them.
Also, on the timing for betting in this presidential election, I would not push the button until we have reached the final days before people are called to vote. We all know how unpredictable these things are.
Let us see how both parties react to the accusations of a rigged election, when they start to happen again, by the end of the campaign.
In fact, things are like that, because I don't see that things are Going to prosper with the former lawyer either, more so now that they want to tarnish the career of a person who is quite Relevant in the world, for me personally I see Ttump as the strongest candidate of all, I don't know if Biden wants to run for re-election, or if someone else comes out, but for me the one who can do things better will be Trump, I would like to see if he can fix the conflict between Ukraine and Russia, although this is going to change many things at an economic level, but at the point of economic recession Trump will catch it very badly, but the advantage is that he has too high a financial education,he will be able to find solutions.
Joe Biden is already officially running, perhaps you missed his announcement.
Also, one of the strong points about Trump is that he is a natural negotiator, he managed to prove it while dealing with Mexican diplomacy (according to him) and also trying to deal the the leader of North Korea, but it would take him more than being a good negotiator to stop the invasion against Ukraine. Putin would likely ask for concessions and perhaps part of the captured territory to be officially recognized as part of Russia. I do not know what Trump would do in that case.
The Ukrainian government would not accept such terms.
