Meanwhile, Spain uses exclusively paper ballots, counted by ordinary citizens who were randomly selected for "election board duty" in their local voting sector (akin to jury duty in the US), and easily finishes counting more than 99% of the votes cast before midnight on the day of the vote. You can go to bed and expect no major upsets when counting is finished, other than the occasional swing of a single seat from one party to another when the d'Hondt assignment was very close.

And this is all for a country of 48 million people (23% more than California), counting votes to fill a 350-seat Congress composed of 50 multiple-seat constituencies of varying size, from 37 to 2 (plus 2 FPTP seats), as well as 208 Senate seats which are voted by check-box selection.

It is truly baffling how some US states manage to take so long to finish counting a handful of FPTP positions in federal elections: 1 president, a couple dozen representatives, and 2 senators.
