What it did was to raise the hope, the feasibility of Hillary's campaign. AND, of course, prime the pump for increased contributed campaign funds.
What it did was prevent Obama from decidedly derailing the Hillary campaign, allowing her a regain momentum. Of course her remarks that she has 'captured' the big states, that she is more electable may influence the super-delegates to again swing to her camp.
What it did was place Hillary on the media's page 1, in the position enabling her to suggest Obama as her VP running mate, thus possible creating a truly formidable ticket against McCain.
What it did was deem to Hillary the 'comeback' title, presenting her with a persuasive argument for 'do-overs' for Florida/Michigan.
Or not.
