“Arizona is geographically large, but its population is concentrated in Maricopa County (Phoenix). About two-thirds of the vote comes from Maricopa. Voters there, as in other suburban areas in and around big metro areas, have soured on Pres. Trump. Biden leads Trump there by six points, 46 percent to 40 percent. In 2016, Trump carried Maricopa with almost 52 percent of the vote”
“Another troubling sign for Trump in Arizona is that GOP voters are not as committed to supporting him as they are in the other Sun Belt states. Call it the revenge of former Arizona GOP Sens. Jeff Flake and the late John McCain, two of the president’s most vocal critics. Only 73 percent of Arizona Republicans say they are definitely voting for Trump, with 9 percent saying they are probably or definitely voting for Joe Biden. In North Carolina and Florida the GOP defection rate to Biden is about half as much (5% in North Carolina and 4% in Florida). Meanwhile, 81 percent of Arizona Democrats say they are definitely voting for Biden with only 1% saying they were probable Trump voters” – Amy Walter.
