They were literally one of the very first things he got rid of and now all of the voting infrastructure is controlled at the state level by partisans who have shown loudly and clearly that they have no interest in playing fair.
Putting all of your eggs in the free and fair elections category is genuinely not a credible plan at this point.
And of course, the Federal government isn't involved in the logistics of voting at all. It's run by thousands of local governments.
You can't stuff hundreds of ballot boxes without election monitors noting the discrepancy in number of voters. Even if you could, you can't add more ballots than people visited without the election monitors noticing or remove them for the same reason.
Since voter names are crossed off and publicly recorded as voting, stuffing a ballot also box risks discovery if that person tries to vote or sees themselves on the list.
Since votes are tallied and reported as counts happen at the precinct level, again, with election monitors, there's no easy place to alter votes. The sum of the precinct totals has to be the final result.
Then there are the automatic recounts which have to match the originals or one risks discovery.
The only real scalable attack is through electronic voting machines without a paper trail - which is why they should be banned. Well that and any ranked choice races for the areas that have them (since they have to be tallied centrally and aren't auditable in any reasonable way). Anything else has a high risk of discovery.
