Two things that come to mind that are not directly related to the running as an independent candidate issue, except they sort of are, because they are issues that Bernie will confront along the way:
1) I asked the other day, but it went unaddressed, no replies: What if Bernie does not get a majority and what if the party will not change the rules to have the nominee with the plurality win? And/but none of the other candidates will stand down and drop out or release their votes. So you have a Mexican standoff- so to speak. The process just hangs there with no majority regardless of how many vote rounds they have. For example, biden delegates just say "screw you, I am not yielding to a commie or bloomberg or whatever."
I asked if anyone knew what the DNC rules of the road were there or if they will have to make them up as they go along. Because that is another area where mischief can set in big-time. You can argue that the dnc would then be forced to change the rules and allow the plurality candidate to be the winner. Not so fast though Sparky! The dem party does not roll that way. I can see them booting it to their executive committe/governing board, whatever it is called and letting them decide with the inclusion of the superdelegates from all the states. Short answer, I don't know but I would expect something cheesy and sleazy.
2) Anyone thinking of running third party will have to think through how this stupid arrangement that lefties set up in regard to doing a workaround on the electoral college would play out with three major contenders in the race, the dems, bernies socialist party, and the republicans. You know some of the clown states have enacted legislation such that the party getting the popular vote gets all their delegates. Y'all may or may not recall that I argued that this is all fine and dandy as long as they think that the dems have a better shot at the popular vote but that if a scenario ever arises where the lefty vote is split or for some reason Trump get the popular vote by the pantload you will be seeing the little geniuses in all those states suddenly scurrying around like rats yelling "my god, what have we gotten ourselves into."
If Bernie ran as an independent the lefty vote will split between bernie and the dnc party and most of the popular vote will go to Trump by far in that divided scenario. So then the lefty vote is divided between two parties BUT THE STATE LEGISLATION PREVENTS THEM FROM CASTING THEIR ELECTORAL VOTE FOR ANYONE OTHER THAN THE ONE WITH THE LARGEST POPULAR VOTE. ie. trump.
I don't know. I have not really thought all that through. But be careful Tards, you are not all that smart. As usual when you all-knowingly try to tinker with the Constitution, it just makes things worse. The constitution does need to be amended from time to time but there is a process for that, and the state legislation electoral college workaround is not such a process. It is just some stupid back door bondo and duct tape "get-trump" solution that has not been thought through.
