President Trump is guilty of being a Republican. For proper context, we have to look at the incident with John Kerry's 2004 VP running mate John Edwards. Edwards' wife Elizabeth announced that she had breast cancer the week before the 2004 election, which Kerry/Edwards lost.
Edwards later ran for President in the 2008 Democrat primaries. He was getting the sympathy vote because his wife had announced that her cancer had returned. Early in the campaign, the National Enquirer discovered that John Edwards was having an affair with campaign photographer Reille Hunter, and ultimately had a love child with her. Edwards eventually dropped out, the charge of cheating on his dying wife was too much for even a Democrat to overcome.
Allegedly, Edwards was paying Hunter to keep quiet about it, but it was eventually discovered. People questioned whether the payments to Hunter amounted to illegal use of campaign funds, but the Edwards campaign argued that cash is fungible and it's hard to tell which cash - campaign cash or Edwards' personal cash - was used for the payments. Edwards eventually went to trial in federal court in North Carolina and was acquitted on the count of misuse of campaign funds, and two other counts were a mistrial. The DoJ declined to retry those two counts.
If President Trump were to be indicted for misuse of campaign funds when he had billions of his own (and no love child to hide), it would be in a New York court which would be hostile to him.
Still, the spectacle of trying President Trump on the same charge that Edwards was acquitted on would twist the liberal talking heads into knots, especially when no child was involved and Trump didn't need the campaign cash to pay anyone off.

An excellent summary.
