The upcoming primaries in WV and Kentucky will give Hillary a clear picture of the support she has. Hillary is expected to win handily in both of those primaries. If she loses or wins by a squeaker as she did in Indiana, it maybe time for her to consider bowing out. However if she does as expected and finishs stongly that makes her still viable for the nomination. It will show that her support has not erroded and that Obama still is not able to penetrate the White Blue Collar vote. The rules commitee with its determination of the FL and MI vote will be the next stop on this road to the nomination.
