Presidents tend to appoint members of the opposite party to boards like the FEC.

Do you have any evidence of that?

It's certainly not true in this case. Trump didn't appoint Democrats. Commissioner Cooksey, prior to his appointment, served as general counsel first to Senator Ted Cruz, and then to Senator Josh Hawley. Meanwhile, Commissioner Trainor worked for the Donald Trump campaign, and served as general counsel to the RNC platform committee, and then later was the assistant general counsel for the Texas Republican party.

These are Republicans.

It should have taken 5 minutes to look at his federal paperwork.

Not sure why the laptop would have led them to look at the paperwork for a 2018 gun permit application - but regardless, it's not the paperwork that's the time-consuming part of preparing to file these kinds of charges. You have to obtain evidence about his drug use back in 2018. It's easy to prove what he filled out on the form. The hard part is proving that the information was false, and known to Biden to be false, at the time the form was filled out.

And once more, with feeling - if Biden did in fact criminally lie on that form, I have no problem at all with him being prosecuted for it.
