My current working theory is that they ran up the score in states where they had enough control to do that.
I was trying to figure out [doing my 50-state Obama 2008-Biden 2020 county comparison] why the turnout in Massachusetts was so big in the counties they absolutely OWN. Markey had the Senate race in the bag, 2,357,809 to 1,177,765 [66% to 33%].
They won all the US House seats in Massachusetts.
Then, I checked my 2008-2016-2020 US states spreadsheet.
Hillary got 91,000 more votes in Massachusetts in 2016 than Obama got in 2008.
Short Bus Biden got 478,000 more "votes" in MA* than Obama 2008.
Figure that Hillary 2016 and Biteme 2020 got less thean Obama 2008, in reality.
Means half a million in Massachusetts alone. When you start adding states like that to the big vote harvesting states [California, Texas, Florida, Arizona and Georgia - 6,850,000 more "votes" for those five than Bammy got in '08], the numbers add up quick.
Yes, this makes sense.
Talk Show host out of MA Jeff Kuhner, AM 680, WRKO, 6am to 10am EST has always said that MA is more Red than we know, he has said repeatedly that the Influx of Students in the various Collegiate hubs like Amherst but especially Boston are totally fubaring the real citizen vote.
Now a 1/2 a million kids?
No, but add Motor Voter and all the "undocumented" they are taking in, this all adds up. Including their old tricks like getting votes from mental health institutions, nursing homes, 2 Western MA favorites. I know, I escaped that part of the state years ago...
