Most of the swing was fraud, plain and simple.
Since the DemoKKKrat Media is in on it, it doesn't get exposed.
Sabato dropped the ball in the 2016 election because he and his fellow KKKrats figured it was "in the bag" for Felonia:
Clinton 322, Trump 216; 50-50 Senate; GOP holds House
- Larry "The KKKrat" Sabato
Now that the Fraud Machines in Wisconsin, Michigan & Pennsylvania have been fixed and the Once And Future Fraud Machine in Northern Mexifornia [KKKalifornia, Nevada, KKKolorado, Arizona & New MeKKKsico] is starting to hum, 2020 is beginning to look like a blowout for the KKKratzis.
no doubt they intentionally supported HRC, but in the past they were accurate in 2010, 2014 GOP House & Senate control.
Months ago the open house races losses were predicted as well as endangered GOP incumbents. Didn’t most GOP seats called a Democrat Pickup happen. Large # of Toss Ups got moved Dem gain before election. (Some here thought GOP would lose than 10 seats and gain far more in Senate. )
I believed months ago few to none Senate Democrats would be listed as Tilt GOP rather than Toss Up.
