Though it is far too distant to yet predict which candidates will earn their parties' nominations, I am speculating a "What if" scenario...
"What if" Hillary Clinton does win the Democratic Party nomination for President of the United States? With ghosts of elections past occasionally running through my memory, I made myself quiver when the recollective thought of Retired General Wesley Clark surfaced. Because it was at that moment that I was also wondering "who"-if Hillary might win the nomination-would she ask to accompany her as Vice President.
I then began reasoning, "Why Wesley?"
The all-too-obvious. Because he could (or might) convince a reluctant Hillary voter to elect him Vice-President.
