Arizona’s been 55% R / 45% D in popular votes for a while and the current congressional representation is 5R / 4D.
That’s about as close to the right numbers as you can get. Of course that can always change next election cycle.
In the 2012 election, the first to be used under the new district maps, Republicans held only 4 of the 9 districts despite taking 54% of the two-party vote — now, that’s a partisan Rat gerrymander.
In the “landslide” Republican election of 2014, CD #2 did flip the right direction and the delegation is now 5R/4D as you noted.
But the so-called non-partisan redistricting commission, in actuality controlled by Democrats, created 4 hyper-Republican districts, 2 solid Rat districts, and — their crowning achievement — 3 marginal districts (1, 2 and 9) which although marginal *clearly* favor the bad guys.
An unbiased commission would have created an easy 5/4 split for the Republicans and a map created by a Republican legislature could have made it 6-3 (or at least 5R/3D and 1 marginal favoring R) with only a small amount of creativity in drawing the lines.
