Hmm. Warren as VP pick is increasingly looking like
the best and most likely option.
To me, that would be an extremely dumb thing to do.
In some ways, it makes sense... she's a capable politician, and her left-wing credentials may help bring some of the more progressive Democrats on board. She would make a good VP (or even a good president).
But, there are problems. In addition to the chance the Democrats could lose a senate seat (A bad-enough prospect with Moscow Mitch still lurking and the chances of the Democrats taking the Senate to be slim), there is also her age.
The Democrats really need to string together multiple terms in the white house. There is a good chance that, being in his 70s, Biden may only be a 1 term president. Usually the vice president has the inside track at being the next presidential nominee (Bush after Reagan, Gore after Clinton), and if they pick the right candidate the Democrats may even be able to string together more than 2 terms. (Biden for one, his successor for 2 terms.) But at Warren's age, she herself may not be able to assume the nomination following a Biden presidency. The result may be another messy set of primaries that divide the party again.
Then there is the issue of demographics.... Biden is already doing well with the senior citizen's demographic. They need to appeal a little more to younger voters.
I think the Democrats would be much better going for a younger woman (a little further to the left than Biden), who is either a gov., a member of the house, or a senator from a Democratic-friendly state (so that they won't lose a potential senate seat.)
