You're mixing things up a bit. The "34 felonies" (really should have been one felony but they used creative methods to bump it up to 34, likely to make it look like a bigger accomplishment) wasn't the financial documents case, and it wasn't brought by Letetia James. The "34 felonies" were about violations of the Federal Election Campaign Act regarding Trump allegedly paying off Stormy Daniels to avoid hurting his election campaign back in 2016, and it was brought by Alvin Bragg.
That case had serious issues with it, as explained
here (or if someone is going to complain it's from a conservative (Andrew McCarthy), see a similar but more neutral examination by Vox--not a source favorable to Trump!--
here), but Bragg benefited from who appears to have been a biased judge (Merchen) and--it should be noted--Trump himself. (Regrettably, both articles are behind paywalls now--the Vox one wasn't before--though the first one at least can be read without subscription if you haven't read two other articles this month) Despite exorciating Merchen as biased and aiding Bragg, Andrew McCarthy still says "Team Trump has presented one of the most ill-conceived, self-destructive defenses I have ever seen in decades of trying and analyzing criminal cases." The issue, as explained in the articles, is that Trump opted not to use a number of defenses that likely would have helped him in the trial, but probably would have hurt him politically. I'm not quite as familiar with the Letetia James case against him but that one looks to be questionable also, and if nothing else the actual fine given to Trump was absolutely outrageous.
Now, I'm not "MAGA", so perhaps I don't count towards what you're saying, but from my understanding of the cases, my opinion is that the prosecutions by James and Bragg were blatant lawfare, and ironically probably helped Trump win re-election because (1) the various problems with them would have engendered sympathy for Trump as victim of lawfare, and (2) due to that perception, the other cases against Trump that didn't make it to court would get mentally lumped in with those lawfare cases even though they were much more credible. However, it also looks to me like the case against James--and Comey--are
also lawfare, at least based on what we the public know, and probably of even lower validity than the cases against Trump. McCarthy, who again was harshly critical of Bragg above,
has also written a bunch on how little sense the Comey indictment makes by the information we currently know. I'm not as familiar with the case against Latetia James, but that one looks questionable to me also. It could be that they do have some amazing evidence against them, but based on various signs (e.g. a Trump loyalist who's never prosecuted a case before is apparently in charge of these) they look to be weak cases based on vengeful prosecution.
