I've got no idea on this one.
The whole arguments for not picking a reporter who lost a bid for Governor, or a second-term Congresswoman who is just a trainwreck (the Atlantic had a great profile on her, which gets into the potential psychology) might not be understood by someone with Trump's lack of sense.
From a legal standpoint, there can be arguments that what Trump did is wrong but not illegal. There's a reason the charges took so long, and I don't think it's a conspiracy to delay a trial until the general election. If legal experts took years to make sense of everything, we can't expect civilians to understand it immediately, especially given all that they're going to hear in bad faith, as well as legitimate areas of uncertainty.
