He's the Governor of California, Governor of a state is a fairly common path to the presidency, Bush was Gov. of Texas, Clinton Gov. of Arkansas, Reagan Gov. Of California. He's also, not past retirement age, and has really big swings in polling in his favor whenever he does a debate or town hall, he's one of those rare politicians who actually answer questions and sticks to policy and data often without talking point word salad, or wasting time with personal attacks.
Wow, I didn't expect someone to say such good stuff about him. That's cool! Glad that California has a good Governor. Also, I didn't know that Bill Clinton was the governor of Arkansas of all places lmao.
