I kinda get the feeling the DCCC is punting on the special election, and is saving their time and energy (and money) for the 2018 general instead. We'll see though.
They're clearly not; Ossoff has --
already -- set a record for fastest online fundraising for a congressional candidate, beating Elizabeth Warren's 2012 campaign.
Can he win? This area is very Republican downballot (it was the first part of Georgia to even consider supporting Republicans, back in the mid-1960s, and was already pretty solid for them by the time Reagan came along), but Trump is weak here, and it's demographically consistent with the sort of place where Trump's approvals have probably slid since his inauguration. I think it'll depend on how the Top Two primary shakes out -- I think a D v. D top two is an underrated possibility, that Ossoff might even be favored against a few of the candidates running more Trump-friendly campaigns, and that even against the others Trump can be used as a cudgel. This district is not KS-4; this is a place where the strategy the Democrats want to use could actually work (though we'll see in practice).
I'd still put it as Leans R or so. But Ossoff is definitely in with a shot.
