Now, it'd be better if he simply got prosecuted for the initial crime. Absolutely agree there. But I'm not sure that "I can avoid prosecution for campaign misdeeds by committing them and then waiting to pay people back until after the campaign" would be a great precedent.
The judge summarized the case for the jury as follows:
> The allegations reflect in substance, that Donald Trump falsified business records to conceal an agreement with others to unlawfully influence the 2016 presidential election. Specifically, it is alleged that Donald Trump made or caused false business records to hide the true nature of payments made to Michael Cohen, by characterizing them as payment for legal services rendered pursuant to a retainer agreement. The People allege that in fact, the payments were intended to reimburse Michael Cohen for money he paid to Stephanie Clifford, also known as Stormy Daniels, in the weeks before the presidential election to prevent her from publicly revealing details about a past sexual encounter with Donald Trump.
That summary implies that paying off Stormy Daniels "to prevent her from publicly revealing details" about the affair was the unlawful act. But under what law? And why wasn't he just charged with that law directly?
Basically, the crime alleged was violating a NY election law saying that you can't try to influence an election through "unlawful means". They provided a sampling of said unlawful means: violating federal campaign contribution limits, falsifying other business records, and violating state tax laws about how the reimbursement to Cohen was handled. The jurors didn't have to unanimously agree about which of those things they think he actually did.
The reasons to not charge him for those separately would seem to be respectively: 1. that's the feds job, 2. statute of limitations expired for the non-felony falsifications during his presidency when he couldn't be charged with anything, and 3. Cohen directly committed the tax crime so all Trump's guilty of is conspiracy to commit a really niche bit of tax misrepresentation that didn't actually cost anything.
The unambiguous bit is that he definitely falsified business records, and so the squabble is over whether he's guilty of a misdemeanor or a felony. It was apparently persuasive to the jury that he did the felony version.
