There is no requirement that anybody be even a registered voter, much less a member of any political party to participate here, Henry, but do you really want a Pelosi/Reid or Pelosi/DiBlasio ticket? Why?
Remember, we're talking about a Democrat ticket. We are not talking about the outcome of an election for the actual office.
I do see Pelosi/Reid as being far more appropriate for The Democrat Party than either Ms. Clinton or Ms Fauxahontas. Ms. C is too old and appears to have issues related to her falls. Ms. Warren - just too phony. She has made a fool of herself over the tribal issue which she has substituted for any kind of experience beyond money manipulation.
Pelosi and Reid have extensive government experience. We may not like the outcome of that experience but neither would require four years of training wheels to tackle the job.
I tend more toward DiBlasio than to Reid, however, as he has already "made his bones" with his rapid-fire Socialization of New York. True, he is very light on executive experience but he IS articulate and he does know how to dress to suit the audience at hand without giving the appearance of "having to have been cleaned up". Pelosi is young enough that DiBlasio could anticipate her living long enough to show him the ropes but only if he could convince her to allow him to do more than cut ribbons to open parks. I do think he has sufficient chutzpah to make that happen.
Together they'd make a formidable (though not too formidable) pair. I believe their being in the race would make the general election more fair and balanced. Factors of immense value to their probable base.
