Arizona primaries set tense test for GOP hard-liners and Democratic establishment

Arizona's primaries spotlight four high-stakes races that could shape November: the GOP gubernatorial contest where Trump-backed Andy Biggs looks poised to win against David Schweikert after Karrin Taylor Robson exited; the AZ-01 Democratic primary where Marlene Galan-Woods (DCCC-backed) faces Amish Shah amid anti-establishment sentiment (with self-funded Jonathan Treble as a possible spoiler); the AZ-05 race where Sheriff Mark Lamb leans on Trump support in a ruby-red district; and the AZ-04 Democratic primary in which Greg Stanton faces Kai Newkirk as progressives push incumbents. The outcomes could influence the November map and party dynamics in a closely watched state.
