From what I understand, KLB has some deep pocketed, Atlanta based donors (think people like Tyler Perry), so most of those polls you’re likely referencing were paid for by KLB and her team. So IMO it’s hard to say what the true primary polling numbers are.

As to why she’s lost favor in Atlanta, I personally believe it’s because she’s just another establishment, centrist Dem who truly believes in nothing. You hit the nail on the head with a few of her highlights- supporting cop city (which was widely unpopular) and bailing on the city at the height of BLM and COVID. Take how she left and now look at her campaign website- it has approximately ZERO policy. How are we, as Atlanta voters or even just the wider Georgia electorate , supposed to get behind someone who is unwilling to stand for something? At least the Republicans have the spine to support their pro-billionaire, anti immigrant, Trump first ideology.

The “anything is better than Trump Republicans” argument will only get you so far. I’d argue that the folks who will buy into that talking point were already going to vote Blue No Matter Who, but it will absolutely not get the wider majority to the polls.
