NE, KS, and AK. If it counts as a red state (probably doesn't), then AZ too.
Georgia has to be up there.
Georgia isn't exactly a "Republican state" anymore. Depending how you define it.
Georgia has only become less of a Republican state because of how anti-Trump it is! The GOP has still controlled GA-Gov and the State Legislature for >20 years.
Not true. Trends in Atlanta had already shifted the state noticeably leftward prior to Trump's entry to the national stage, from 2004 to 2008/2012 (Bush+17 to McCain+5 and Romney+7). Even without Trump GA would still have become fairly competitive by 2028 or 2032. The Trump factor merely accelerated the leftward shift.
Consider the fact that Trump's not the only GOPer to have lost in GA - Democrats have won the three most recent Senate elections as well.
The only reasonable conclusion regarding GA's politics now is that it's a purple state - possibly with the caveat that it has an R bias in state-level elections and D bias in federal elections (using the last 2 election cycles as a sample).
