Blake Masters' favorite senator won't endorse his second Senate campaign in Arizona

• GOP candidate Blake Masters is reportedly planning to run for Senate again in Arizona.
• But two of his closest ideological allies — Josh Hawley and JD Vance — declined to formally back him.
• "I've got to focus on my own race," said Hawley. Kari Lake may also run for the Arizona Senate seat.

If Blake Masters mounts a second campaign for Senate in Arizona, he may be going it alone this time.
