Correct. Ossoff is the favorite because some Republicans who voted for other candidates will skip the runoff.
Not in this district. This district voted overwhelmingly for GOP Senator Johnny Issacson in Nov 2016. Ossoff one shot here was running against a split GOP field and hoping for an overwhelming Democrat turn out against a low GOP turnout to avoid the run off.
The reason Trump under performed in this district is the Never Trumpers had an impact. This is a stolid GOP E district. They showed up to vote for Issacson and then did not vote for Trump in Nov 2016
He won’t win. The Democrats threw everything into this race. All the dirty tricks were used. Also, now people know he doesn’t even live in the district. And he’s running against a woman.
The Democrats best bet is to get another Republican to run and split the vote.
