The evidence is overwhelming that since Super Tuesday, the minute that Clinton steps foot in a state, her numbers start to plummet.

Richard Cohen writes in The Washington Post:

Big-money Democrats have been on the phone of late, and their conversations have been on how to get Clinton out of the race. Some of these Democrats were tepid Clinton backers to begin with, wishing to go with the presumed winner or responding to the soft extortion of Bill Clinton and his allies. But others were sincerely committed and now fear that the Clintons, she and he, will not know how to lose -- and will take the Democratic Party down with them.

My cards are already on the table. I don't think that Clinton can win the nomination, but even if she does, I don't think she will win the general election. That would become apparent as she starts to campaign in states that have yet to see her. The harder she works, the worse she does.
