Let's remember: if the Governors race (likely) goes to a runoff, it would be in December. The runoff for Senate would be in January.
What the hell?!?!
Yeah, GA's changed its rules since 2008. The Senate Runoff wouldn't be held until January 6. The new congress convenes on January 5, so this could result in a really awkward situation, where the republicans could have a 50-49 majority when the new congress first convenes, but then a couple weeks later once the GA results are certified, we could have a 50-50 senate, which would technically be democratic control.
