Last night's results mean the pressure on her to get out has been turned up a few notches. As MKH noted, George McGovern is urging Hillary to get out. He is, after all, the expert of how Democrats can lose a general election by a landslide -- so maybe his advice is good?
In any event, Hillary needed to end speculation that she might drop out. As such, her speech today in Shepherdstown, WV (my alma mater), was a wise move. It sent the signal that she is, in fact, still in this thing. That will likely stop the speculation that she is about to get out. For now.
