If Bernie Sanders wins the nomination, Wall Street CEOs and hedge fund managers have already threatened to cut off the money spigot. Some of them even threatening to back President Donald Trump, oh the horror. I would not be surprised if they launch Super Pacs attacking the Socialists Bernie Sanders and Elizabeth Warren. These guys are not playing since, they run the Democrat Party.
Where the Wall Street power players are going to outsmart themselves- or many anyway- is by backing Biden because he is the embodiment of steady eddy and allegedly moderate. But then Joe has to take on a progressive vp in order to assuage the far left, and then they think " well wtf, the vp doesnt do anything anyway."
But then Joe goes tits up just based on his current trajectory. That could come in the form of going kaput outright or remaining in the office and the vp becomes the true power player just holding up cue cards or just cleaning up everything he say. If they support Joe for president on a ticket with stacy abrams, pocahontas, or someone of that genre then what do they really have in the Oval Office for the long haul - and then the vp is also titted up to run in 2024.
This is not a pretty scenario for them. There are many ways to rearrange the deck chairs on the Titanic in a way that they work just fine and are comfy for a while. Until they suddenly aren't comfy.
