> My understanding is that one group literally believes that the President was elected undemocratically, and are trying to correct for the mass fraud that was used to install the current President illegitimately.

That blend of belief is shared by a subset of militants, but that's the result of the years-long propaganda campaign devised by the militant group's leadership in preparation for the election campaign.

We're talking about a política group which dedicated itself simultaneously to sabotage the election campaign by attacking voting methods believed to be disproportionally and massively favoured by other candidates , and included the preparation of a coup to overthrow the political regime to continue holding power.

The myth about fraudulent elections, which preceded the election by over a year, was made up by the militant group's leadership, and we should not interpret it as a reasonable and natural excuse to push a self-serving myth.
