"We recognize that, in the next four years, our decision may cause us to have an even more difficult time. But we believe that this will give us a chance to recalibrate, and the Democrats will have to consider whether they want our votes or not."
That's gotta be one of the strangest reasonings I've heard in a while.
Again, you don't understand what contradictory means. Does saying the sun can explode tomorrow and saying it has a low chance of doing so contradictory? Similarly, saying a third party can win if people switch their votes away from the Dems is not contradictory to saying there is a low chance of that happening.
You're doing a logical fallacy by assuming that statements made about possible alternative events are equivalent to statements that claim the event is likely to happen.
