Georgia isn't a blue state. Georgia's House of Representatives is Republican majority (100 to 78). Georgia's Senate is Republican majority (33 to 23). Georgia's Governor, Lt. Governor, Secretary of State, and Attorney General are all Republican.
I guess you're thinking of Ossoff and Warnock? They occupy Georgia's two seats in the United States Senate. Yes, they're Democrats. But that's nothing really to do with the state. Georgia also has fourteen seats in the United States House of Representatives--also nothing really to do with the state--and nine of them are occupied by Republicans.
