This is why the GOP needs to slow the RATS role the next few days. They will need Trump's coattails if they plan to get the Senate back in 2022. Trump brings voters to the table. Without Trump the GOP is screwed, they need to let more information come out over the next few days and let more info on ANTIFA’s involvement get into the system. The GOP is dead right now, if they go after Trump they will be buried.
I think you're wrong in this assessment. The 2018 election cycle was an absolute disaster for the Republicans even in the Senate races.
Yes, the GOP picked up two seats in 2018. But that was an election cycle when they should have picked up more. There were 24 Senate seats held by Democrats contested in 2018, and only 9 held by Republicans. Look at all the states that Trump won in 2016 where the Democrat won a Senate election in 2018:
Arizona -- which turned out to be a complete disaster because the governor promptly appointed the loser (Martha McSally) to fill John McCain's old seat until 2020, when she suffered the ignominious distinction of losing BOTH Arizona Senate seats for the GOP
Michigan
Montana (how the hell does Montana NOT vote for a Republican?)
Ohio
Pennsylvania (GOP candidate Lou Barletta was Trump's biggest supporter in 2016, and he got his ass kicked in 2018)
West Virginia
Wisconsin
As I see it, there is far too much emphasis being put on the disastrous Senate elections in Georgia this week. The Republican Party effectively lost the Senate in 2018 when they didn't capitalize on an opportunity to make more gains in a year when they had so few seats to defend. It just took two years for this to materialize.
