Maybe it's different in the US context, but the "never had a real job" attack doesn't seem like a dog-whistle to me and is familiar as an attack by populist 'outsiders' against politicians. Still incorrect and dumb though, regardless of intent.
Anyway while Republicans seem to have this idea that suburban dissatisfaction with Trump is just because of his personality and they are supportive of his agenda, the 2018 midterms should have made them think again. Especially since Perdue isn't even going to criticize Trump on 'personality' grounds. So, since he votes with Trump 96% of the time, he's going to be tied to Trump and do badly with suburban voters. Making no effort to assert his independence and try to appeal beyond the Trump base seems unwise. Given Trump is still favored in Georgia, albeit narrowly, Perdue could hang on, and even if Trump narrowly loses(say Trump loses 49-48 to the Dem), Perdue may end up able to pull off a runoff victory(so 49-49 in the general and 51-49 in the runoff), however Perdue is unlikely to outrun Trump by much and so is vulnerable, especially if the national environment ends up favoring the Democrats.
Kemp with all his shenanigans outran Karen Handel and Rob Woodall. White people in suburban Atlanta are leaving the Republican Party period. Trump may carry Georgia since he doesn't need 50 to get electoral votes but I believe the Dems will pull Perdue into a runoff and then both sides will blow their loads on the runoff when it eventually determines balance of power in the Senate.
Minor quibble, but I'm pretty sure Abrams did slightly better than the Democratic Congressional nominees in GA-06 and GA-07. She won the 6th by like 2 and won the 7th by half a point IIRC
Abrams won GA-06 by 3.5% and won GA-07 by 1.4%
That should have carried Bordeaux over the top, IMO.
Probably, but it still does go to show just how few ticket-splitters are left in the Atlanta suburbs. There really weren't that many voters splitting their tickets between Abrams and Woodall, just barely enough to let Woodall scrape by through the skin of his teeth. Contrast that to Brian Fitzpatrick winning by 2.5% in PA-01 while Wolf and Casey were romping in his district.
This is why when GA goes, it isn't coming back.
