If you approach elections with this mindset, you'll be ending up with a candidate far more pro billionaire that Steyer. We shouldn't forget that Roosevelt was also from the then billionaire class.
That being said, you shouldn't feel obligated to vote. It's up to you to decide if that really works for you or if you even believe voting can.make a difference, or just don't want to for whatever reason. It's your choice to participate and always will be.
But if you are going to vote, Steyer is obviously the preferred choice.
And on Porter. She fell off hard. She both doesn't stand a chance and needs to drop out today and endorse Steyer, and would be a shittier candidate and governer than Steyer.
