I always loved this part of the movie.
Remember when Q said that they had to "show the American people" before they would be willing to change?
Election safeguarded.
The American people had to witness the election fraud first hand.
The final nail in the coffin.
Canada must wake up next due to proximity, then willingly join the US in the new United States of North America.
Or just annex Canada by force, in a few hundred years they'll be grateful.
