I noticed this when they show the 2020 vs 2016 comparison chart on TV.
There is a TOTAL of 538 Electoral Votes, which is how we get the MAGIC 270. Half of 538 is 269. 270 is one above that.
So, why the discrepancy … & the Biden/Trump tally MIGHT end up different at the very end.
Electors who did NOT cast their votes like they are supposed to!
That is what happened in 2016. There were 7 faithless votes. Now it should be clear.
Search ‘Biden’ & ‘Trump’.
