My guess is that they were trying to bully/threaten other countries into financing/backing them in an overthrow of our government. If we had a lesser man in office, their plan may have succeeded if only because the other countries were afraid of them. But I bet POTUS made it clear that any countries helping them would be considered assessories to the crime and would feel the wrath of the US.
Because Dems are too stupid to retire. They actually think they can bully/bribe/manipulate their way out and still win.
Delta also means D, the 4th letter in the alphabet. Maybe this is one of four rolls.
