To whit, "believing that your life got substantially better or worse following an election" would not be a religious belief. This is because it can be tested, and would have a simple cause/effect based in physical reality. It might be an intangible "I feel better about things because I know people agree with me, and think that people in positions of political power will support my interests" -- but there's nothing supernatural about that.

As was said, if you want to redefine the word "religion" to mean "any sort of belief system", then sure, go for it. It's a great way to troll and provoke arguments.
