Military involvement over electoral theft is bad for the country, worse for democracy.

Calling on the military to prevent an electoral theft of the presidency is a far worse thing than the electoral theft itself would be.

Let's assume for a moment that the Democrats did in fact steal the presidential election.

1. That theft would have taken place in just a few states where the election was going to be close enough to make the theft both possible and plausible, states where the election was a virtual coin toss.
2. Trump's prospective victory was only going to be possible because of the electoral college; he in no way was going to be the preference of a clear majority of American voters.
3. The two major parties trade the presidency back and forth, and will continue to do so in the future; the alleged theft would not presage a permanent takeover of the executive by the Democratic Party.
4. As voters generally aren't making reasoned choices anyway, presidential selection could be managed by an actual coin toss without causing any real harm to the country's future (at least compared to any harm caused by letting masses of unreasoning people vote).
5. The presidency should not be seen as the holy grail of American politics - as virtually America itself - but as just an office held by temporary functionaries.
6. All that being the case, the theft of a presidential election, while wrong and appropriately to be punished if proven, would not be catastrophic.
7. Military intervention in electoral politics tends to leads to authoritarian military government, which is frequently catastrophic.

Therefore, even if Trump truly did have re-election stolen from him by Democratic fraud, it would be better for the country and for democracy - if it cannot be proven through legal proceedings - to accept the outcome rather than call for the military to help him stay in office. No one person's four years as President is remotely as important as keeping the military out of politics. The Republicans could then focus on ensuring that it's harder to commit electoral fraud the next time.

But Democrats don't get off free from criticism here, either. Every Democrat who has called for the military to remove Trump if he refuses to leave the White House is just as guilty as Trump himself for thinking about involving the military in our electoral politics. I don't know just which civilian police agency would be responsible for removing a recalcitrant power from the White House (I suspect the Secret Service's Uniformed Division), but it is clear that there are civilian officials who would be appropriately tasked with performing that job.
