This thought came to me reading Legal Insurrection: "Hillary will crumble if Elizabeth Warren just says yes."
I've always felt that Hillary's support is a mile wide and an inch deep. The effort to recruit the Left's Barry Goldwater is an acknowledgement that Democrats just aren't that into Hillary. Are Democrats really going to nominate a first-term Senator from academia who has no experience running a lemonade stand?
Oh, right. That guy.
Update - I just realized I should explain: Martha Coakley is the Attorney General in deep-blue Massachusetts but she lost a Senate bid to Scott Brown then a governor's race to Charlie Baker. Why? As I explained over at Althouse, Coakley just can't connect with voters. And that's Hillary.
