I hope Gavin Newsom. Brian Schweitzer would be equally fine.
I hope Gavin Newsom too. But not for the same reasons you do.
He would ensure an easy Republican victory.
Considering he cheated on his wife with the wife with his campaign manager, he seems like rather low hanging fruit for the Republicans...
Not to mention the highest office he has achieved is mayor. If he won, that would be the least impressive officeholding resume of any incoming President since former state Representative Abraham Lincoln.
