We have previously suggested that a Biden-Warren ticket might be a good way out of the Democrat's current crisis, one of the problems being is that no matter whether Clinton or Sanders were to get the nomination, many opposing Dems would stay home in November.
Interestingly, the conservative National Review mentioned this possibility as well, which led us to consider the unresolved problem of what one would do with Clinton and Sanders. Our best solution: Biden promises Clinton a Supreme Court seat and Sanders gets a Nobel Peace Prize for saving the world from a Trump presidency. To be sure, you need the Senate's approval of a new Supreme Court justice but since Clinton believes she will get anything she wants, that shouldn't be a problem.
Just a suggestion.
