[Firestarter]

Some cynics note that judges have quickly dismissed many of Donald’s “voter fraud” lawsuits, because the whole hysteria is nothing but a charade (without merit in legal jargon)…

Only after a donor reaches the maximum contribution limit for each group — $5,000 for Trump’s Save America PAC and $35,000 for the Republican National Committee — the (rest of the) money will go into legal accounts for Trump and continues to flow to the RNC.
I’m no “expert” at this but this doesn’t sound convincing to me (so I think this analysis is wrong).
$5,000 for the Save America PAC (at 60%) will be reached when a donor reaches $8333.
$35,000 for the RNC (at 40%) will be reached when a donor reaches $87,500.

Leadership PACs (like Save America) have long been misused. They can legally be used to pay for questionable expenses.
According to Adav Noti (former Federal Election Commission attorney):

They could pay (Trump) children consulting fees. They could pay the children’s significant others consulting fees. They could buy Don Jr.’s book, which the campaign can’t do. They could do anything with it. There’s no personal use restriction.

According to campaign finance attorney with the Common Cause, Paul S. Ryan:

This is a slush fund. That’s the bottom line. Trump may just continue to string out this meritless litigation in order to fleece his own supporters of their money and use it in the coming years to pad his own lifestyle while teasing a 2024 candidacy.

These “experts” agree that the money for Biden’s legal fees to defend his election win, is a lot less dubious.
According to a “DNC official”, most of this money goes to the Democratic National Committee’s legal account, which could be used for legal expenses for Biden in this hysteria or to cover the legal and advertising costs for other Democrats: https://archive.is/KBOyK
