It’s interesting that the U.S. Census is conducted every 10 years, presidential elections are conducted every four years, and census results affect the number of electoral votes apportioned to each state. So the 2020 Census was too late to change electoral votes in the 2020 election, but it has changed them slightly in the 2024 election.

From Newsweek (and I haven’t confirmed this from other sources):

Texas was the biggest gainer, according to the Census numbers that were released in 2021. The Lone Star state gained two more votes in Congress and the Electoral College for the next 10 years. Colorado, Florida, Montana, North Carolina and Oregon also each gained one seat, while California, Illinois, Michigan, New York, Ohio, Pennsylvania and West Virginia lost a seat each.

I count 3 votes shifted from states that voted Democratic in 2020 (Colorado +1, Oregon +1, California -1, Illinois -1, Michigan -1, New York -1, Pennsylvania -1) to states that voted Republican (Texas +2, Florida +1, Montana +1, North Carolina +1, Ohio -1, West Virginia -1).

It doesn’t seem like this will matter in 2024, but with the election possibly coming down to just 2 electoral votes in the Democrats’ favor (if they win Pennsylvania-Michigan-Wisconsin and lose Georgia-North Carolina-Nevada-Arizona), transferring 3 more points after the 2030 census could make all the difference in the 2032 election. But that is pretty far away and a lot of things can change in 8 years. For example, the actual people moving from “blue” to “red” states could take their “blue” politics with them and eventually shift their new state into the blue category or at least the swing state category. Maybe 8 years could be long enough to do away with the idiotic electoral college itself, which was created to convince 18th century slave owners to join a rebellion against an 18th century empire. But no, I am not this optimistic.
