Think it would be safe to say that 47 states out of 50 are exactly this. The cities dominated the statewide offices and run the table on federal elections.
And what I find really interesting is how many people still have their heads in the sand about this reality not turning Georgia. Sure Georgia will maintain a Republican legislature forever, probably, but there are about 11 or 12 counties, Blue Counties, that have growing populations. Soon they just might be able to run the table on statewide offices.
That's why Democrats love the XVII Amendment.
