If the GOP lost control of the Senate, they only have themselves to blame.
Kelley Loeffler was a very poor candidate, for starters. Purdue was flawed. But in a traditionally "red state" the onus was on the Democrats, historically they had no chance to win a run off election.
Mitch McConnel put ALOT of effort to ensure the GOP held the Senate, but utter failure due to upstarts Lin Wood and Donald J Trump himself causing more Democrats to turn out, Gops not vote, and end the insanity and more people to turn their backs on the GOP
End result is the GOP lost, it is a party divided and has FAILED. OUCH
