The difference is that in most dictatorships that have "elections", the elections are run by the central government. In the US, the states run the elections. Sure, the US federal government has some levers and influence, but I think our elections are less susceptible to presidential tampering due to their decentralized nature.

Being decentralized helps, but there's still only a few voting machine vendors, still nationalized media, and nobody is checking state ID of the protestors at state elections.

And US elections have been very tight, and the electoral college means that only a few states being controlled is enough.

We also lack an apparatus to overturn a fraudulent election. Even if a judge rules that an election was fraudulent, that's not the same as certifying another vote total nor can it physically remove someone from office.
