Cook Senate Tossups Splits

This is because no party has swept all but one the Tossups ever since cook gives tossup data

2008(R): GA + MS

2010(R): IL +PA

2012(R): NV & AZ

2014: NH

2016: NH & NV

2018: NJ, MT, NV & AZ

2020: GA & GA

in fact, 2014 2006 & 2004 are the only times only one seat deviates, the rest have 2 seats deviating from the rest of the tossups or it's a near even split (from the data we have)

Also, in the infamous 2010 wave Dems swept all but 2 of Cooks final Tossups, make of that what you will (Too early to say now  where the tossups fall FTR).

If the election was held right now I’d say the Dems have a realistic floor of 47 seats, and probabilistic floor of 48 seats, with a shot at 49. But I’d say that the majority is gone if the elections were today.

Note: these are general senate numbers, not ones for specific races.
