Karrin Taylor Robson, a wealthy Republican businessperson who was seen as the likeliest establishment candidate for a crucial Arizona Senate contest, said Thursday that she won't run for the seat now held by independent Kyrsten Sinema.
Robson ran for governor last year but lost the GOP primary to Kari Lake, a Donald Trump ally and darling of his Make America Great Again movement. Lake went on to lose the general election to Democrat Katie Hobbs and said this week she is considering a run for Senate.
