Georgia will be centre of the political universepublished at 19:29 Greenwich Mean Time 9 November 2022

Who a run-off will benefit more depends on what happens in the existing Senate races.
Because in some ways, if the Democrats hold onto those other two outstanding Senate seats that are up, Nevada and Arizona, then they hold onto control without Georgia.
So yes, Georgia would then become a bitterly fought run-off, but not one that's a battle for controlling the Senate.
But if one of those were to go to the Republicans then Georgia becomes centre stage in who gets to run the upper chamber of Congress and its committees, as well as who gets to approve judges - potentially even Supreme Court justices - for the next two years.
So there is an awful lot at stake, with these two candidates here pretty much as neck-and-neck as you can be - just not quite enough to get over that 50% mark.
A lot of money, activists and political advertising will flood this state for the next four weeks, as people try to battle for this seat.
Because the Democrats would definitely like, if all goes well for them elsewhere, to have 51 Senators - not just a 50/50 split - as that would allow Joe Biden a little bit of room for manoeuvre.
The campaign I am sure will be ferocious here, it will be a hard-fought, intense four weeks.
So Georgia will be the centre of the universe politically after today, I think.
