I have noticed a trend where every single race just about seems to come within 5% no matter how pissed off the populace is. Even presidential races. Anything that isnt a clear victory like alabama and deep red states.

If you think about it logically shouldnt it be highly unlikely that the country is split nearly 50/50 every single time. I feel like at least half the close races should be 10 or 20 points different. We know they mess with the algos but is it possible it runs deeper than that?
