Blake Masters is a Republican politician and a candidate for the United States Senate in Arizona. He has a close relationship with tech billionaire Peter Thiel, and wrote the book Zero to One based on notes he took from Thiel's class at Stanford, where Masters got both his BA and JD. Masters resigned from his posts running Thiel Capital and the Thiel Foundation to run in Arizona. Masters is staunchly opposed to critical race theory, and supports a stronger border and the reduction of illegal immigration. He is also tough on crime, and has appeared on Tucker Carlson's show to denounce the increase on crime rates, which he has blamed on Democratic Party politicians like Arizona Senator Mark Kelly. Masters is also a suspicious of large tech companies, much like Thiel, and views them as stifling innovation and as pushing a left-wing political ideology. Masters has also famously stated "you should be able to raise a family on one single income". While not alleging fraud on Election Day in 2020, Masters released a video critical of the coverage of Hunter Biden's laptop and of voter registration policies.

Masters has received significant attention and both praise and criticism. In particular, some on the left have criticized Peter Thiel for his opposition to democracy and his links with the neoreactionary thinker Curtis Yarvin.
