I agree. Georgia and Arizona are both starting to look catastrophic for Republicans.
I disagree on Arizona... it's a far tougher nut to crack. While the SW as a whole has swung to the Democrats, AZ remains completely stuck. Even if a Democrat could win state-wide, that's not that indicative of much. Note that NM has a generally popular GOP Governor but has two Dem Senators and has voted for the Democrat in every election bar one for the last quarter-century.
If you look at the vote share of the Dem nominee in AZ since 2000, it's scarily static - around 44% each time. While AZ's Latino population is growing, albeit slightly slower than TX, CA, NM, CO and NV - the increasing age and conservatism of the white population is keeping pace.
In 2012, Obama got 39% of the white vote nationally - and got between 40 and 44% of the white vote in the SW and Mountain-west states - so even among the white vote Obama did better than he did nationally... but AZ? He got 32% of the white vote, so under-performed his national performance by 7%.
I'm sure AZ will shift as the older white voters start to shuffle-off ... but it's a different dynamic to Georgia. I can see GA voting for the Democrat nationally, well before AZ does.
