perspective

Jennifer Wolak @j_wolak_ 1d

In this midterm election cycle, we spent on a mere $11.9B on congressional races.

which means that Election Day spending still came in below Halloween purchases (where Americans spent $13.5B) and Valentine's Day spending ($29.1B spent).

Will Jordan @williamjordann 2d

99% of House districts moved against president's party this year -- biggest in modern history & clearly a step change, but part of a long term trend towards "universal swing" in House districts (2022 was a non-wave, but similar to 2010 at 84%).

Median district +14D, also a high

case in point: which groups contributed most to the overall swing? white people and old people (just bc they are big groups that shifted about as much as everyone else)

John Sides @johnmsides 4d

Virtually every demographic in the country shifted toward the Democrats in 2026.

But, sure, let's have a thousand takes about The Weird Reason That One Group Shifted.
