Observations:

- Harris did more poorly than forecast in all but three races: DC, UT, and NE-1.

- Her opponent did better than forecast in 32 races.

- Many of Harris's bigger under-performances were in races she won, notably CA. FL and TX are losses with far worse-than-polled returns.

Net average polling bias is 2.68 points favouring the GOP across 56 contests.
