…the early morning hours, on Eastern Time, of Wednesday 11.06.2024.
It will have to do with any states outstanding … and that they may be bellwether/“swing” states which could not be projected by Tuesday 11.05.2024 @ 11:59 p.m. ET.
This also has to do with prevailing party and electoral structure.
My answer is with regard for a 2024 Republican pickup for U.S. President.
I do recall…
In the 2008 Democratic pickup for U.S. President, the 270 electoral votes were reached on Election Night, Tuesday 11.04.2008, at 11:00 p.m. ET.
Due, in part, to a 2008-to-2012 underperformance, but still a Democratic hold, the election was called around 11:15 p.m. ET on Tuesday 11.06.2012.
For the Republican pickup for U.S. President in 2016, I think it may have been the hour of 02:00 a.m. ET on Wednesday 11.09.2016 in which 270 electoral votes were reached.
