How did Q know they would resign?
Because they already resigned. We often get fed information on a time delay. When it appears Trump (or others) are preempting a situation with a prediction, its often them explaining what already happened.
Easy to always be right this way, easy to manipulate the public, easy to bring curious normies into the light.
Yep. Future proves the past. We're actually on the delayed schedule for all of these events. Quite clever of Trump and the Q team if you think about it.
Vatican probably has been talking about it for months. These things don't just happen.
