We managed to go 7 years since the last proposal to partition #California. I just updated #Wikipedia with a map of the latest Republican plan to split off inland California from the coastal counties. (And no, it's never going to happen).

A screenshot of the Wikipedia page for "Partition and secession in California" showing seven maps of various proposals to split up California into multiple states. The most recent one is Republican state assembly member James Gallagher's proposal to split the inland counties of California off into a new state.

A great article from @sightline.org about how Proportional Representation would benefit Whatcom County: www.sightline.org/2025/04/10/w...

A dot density map of Whatcom County showing one blue dot for every 50 Democratic voters and one red dot for every 50 Republican voters. You can see that Democrats are clustered in the city of Bellingham and Republicans are the majority in the rural parts of the county, but the map communicates that every part of the county is mixed politically.

Final update of this chart for day 43, now that the results have been finalized and the Electoral College has met. In the end, Trump has 49.9% of the total vote. The 4.7 million vote gap between Trump and Harris on election night narrowed to 2.3 million by the time all the votes were counted.
A chart showing "Daily presidential popular vote totals in 2020 and 2024, as counted each day after the election". For Biden in 2020, a blue line starts just about 70 million votes right after the election, but gradually grows over 30 days to be well above 80 million. The Trump 2020 line starts at 67 million votes, and it also gradually grows too, but at a much slower rate than Biden's, eventually ending up at 74 million votes. Overall, the gap between Biden and Trump grew from about 3 million votes counted on the day after the election, to a gap of 7 million votes one month later. The 2024 totals show Trump's totals again growing relatively slowly compared to Harris's. While Harris did not overtake Trump's lead in the popular vote, the final results were much closer than they appeared right after election night.

Updated for day 24. The curves are no longer growing logarithmically so I removed the trendline. I think we're very close to the final numbers now.

Unlike in the previous chart, this chart uses a logarithmic scale for the X axis, so that the lines on the chart appear almost straight at the beginning. As of day 24 they are no longer straight on this chart, suggesting that the count is nearing the final numbers.

I updated the chart of popular vote totals for day 20. The lines for 2024 continue to flatten out, suggesting that we are counting votes faster this time than in 2020.

Although it's hard to see on the chart, Harris's 2024 votes (so far) have now passed Trump's final totals from 2020.

There are also semi-transparent lines which indicate the trend line for the 2024 count, if the current approximately logarithmic trend continues. If we follow those trend lines, we see that the Trump and Harris final popular vote results for 2024 will be very close in the end, but Harris will not overtake Trump.

And here is the same popular vote count chart, plotted on a logarithmic scale, with a trend line fitted to each data series. Adjusting the X axis like this means that the trend shows up as a straight line.

Here's the presidential popular vote chart for day 14, compared with where the totals were at this time in 2020.
The gap between Trump and Harris continues to narrow (and Trump is about to drop below 50% of the total vote according to Wikipedia).

After the election, I saw a ton of hot-takes comparing the 2020 and 2024 popular vote totals. But are still millions of votes left to count, especially in places like California.

So I made a chart comparing 2024 so far with the same point in 2020, so you can see how many more votes to expect:

Last month I gave a talk at the State of the Map US conference about our work migrating our famous @stamen.bsky.social OpenStreetMap-based map styles to a modern platform in partnership with Stadia Maps. Now you can watch the recorded video of the talk on YouTube:
