Captain Ed has a good analysis point: "Candidates tied to Clinton don't worry about her liberalism, they worry about her (other) negatives, not least of which is her incompetence on the campaign trail. Clinton has never had to campaign in a contested race before now. She had no primary competition for her first run at the Senate, and faced walkovers in both races. Hillary now has proven herself the antithesis of her husband, perhaps one of the best natural politicians in the last generation. She has become so desperate that her official website now criticizes her toughest opponent for essays he wrote in kindergarten and the third grade."
Indeed. Also, there's this: I never liked Bill Clinton. But I could see how others could (they had to overlook a lot, in my opinion, but...) He knew how to work a crowd, how to turn on the charm, how to appear to connect with people. I don't see any of that charm with Hillary. She's not all that likeable. And now people are realizing she's not inevitable. There are alternatives.
