Republicans only won 1 swing state Senate race last night,Florida. Democrats won Pennsylvania,Wisconsin,Michigan,Navada,Virginia and Ohio,the states that will decide 2020. Democrats came within 3 points in two traditional red states that are usually far out of reach for democrats,Texas and Arizona.
Only an ignoramus thinks that this has anything to do with 2020 especially when Republicans won the more powerful seats and the Dems under-performed in The House.
