The results are especially striking because surely holding everything equal, one would expect Doug Mastriano's appeal to be strongest in the rural+rust belt areas that swung hard in support of Donald Trump: & Oz to be more appealing in the upscale/moderate/cosmopolitan suburbs? 
Lots of things happened around the end of June: Dobbs, bipartisan bills, gas prices coming down, Jan 6 hearings gaining news. The exact proportions of which had an impact on who may remain up for debate. But what's clear is things changed & stayed changed
As a reminder, here is where the 1,053,805 voters live whose mail ballots had already been received and tallied by their counties as of 11/4/22. 
As a reminder, PA mail ballots should *not* be treated as tea leaves to guess final results. All the important variance in this election is going to come from the groups least likely to vote by mail (young voters, urban core voters, GOP only-recent voters)
Basic takeaway: post-Dobbs pattern held. Democratic voter registration finished strong, outpacing Republican net gains by just over 6,000 net voters statewide in the last two weeks. (Note these stats encompass not just new voters but party changers, deaths & relocations, etc) 
Where folks take both yard signs and holiday decor very seriously 
omg it's like a nightmarish mashup of everything I worry about. Progressive grassroots Postcards to Voters here transformed👇into malinformation that furthers false claims regarding mail ballot voter fraud— pushed by shady Fb influencers crowdsourcing local political action 😳 
(as a reminder, more info that any human could want about long term patterns in partisan voter registration in PA is available to you here:
TV/Radio spending in PA GOP gubernatorial primary: McSwain $6.3M + $4.9M outside. White $5.5M. Corman $2.2M. Barletta $1M. 
On the GOP side, the top 3 all had some support everywhere. In part that's about Trump endorsing a candidate who was a poor natural fit for Trump's voters. +Barnette's bio & crossover appeal? Anyway, nothing here suggests Mc/Oz is going to have difficulty consolidating GOP votes 
(Yes I know. What the chart really shows is that registered Dems in pro-Trump precincts were Steve Irwin's strongest supporters: not how they individually voted in 2020. Still—Biden vote was a stronger predictor of precinct-level support for Lee than even, eg, % Black pop. fwiw!)
