● AZ-08: A super PAC affiliated with venture capitalist Blake Masters' longtime allies in the crypto industry are spending almost $600,000 to boost him in the July 30 Republican primary for Arizona's 8th District, a constituency in the Phoenix's western suburbs that's home to what is now the ugliest House primary in the nation.

The opening spot from Defend American Jobs touts Masters as an ardent supporter of border security but does not mention his main rival and 2022 ticket-mate, Donald Trump-endorsed attorney Abe Hamadeh. (Masters was the GOP's failed nominee against Democratic Sen. Mark Kelly while Hamadeh narrowly lost the race for attorney general to Kris Mayes.)

That's quite a contrast from what another Master ally has been up to, though. The American Principles Project dropped over $150,000 on digital ads in the spring labeling Hamadeh a "terrorist sympathizer."
