This is one of Davis' weaknesses. He has a terrible temper. He's been known to explode at subordinates for the slightest offenses. One described a cursing tirade from Davis as "usually while screaming the f-word with more venom than Nixon". He's even assaulted workers! This also extends to his dealings with legislators. One Republican who attended a meeting with the Governor during the power crisis described a Davis outburst as a "symphony of obscenities". Lungren's team never attempted to exploit this weakness. I hope that Simon's team isn't nearly so polite.
