Whereas Ossoff is struggling to make it to the finish line even with all the money thrown his way and a terrible quality candidate.
Yeah, there are just about no indications of this whatsoever. His average lead in the polls has consistently risen since the first round was held, he's capturing not just most of the independent vote but also a good percentage of Republicans (with virtually no observable crossover, i.e. no Dems are going to Handel), and he's turning out thousands of people in that district who have never voted before. So I'm not quite sure what you're basing this off of. If you're referencing how close the race is, then well... duh. That's to be expected in Newt Gingrich's former district. It's historically Republican, and despite Hillary's improvement there it still leans R. That's why Ossoff hasn't gone all gung-ho progressive 'we need single payer and free college and we need it now!' That doesn't make him an unprincipled person or a coward. It makes him smart and pragmatic.
Definitely too much money in the election, though, you're right about that. On both sides. It's obscene.
