Way back when...

...while I was President of the Young Democrats of Washington, one of the highlights was the presence of Brock Adams attending our state convention, where we became the first party organization to endorse his campaign for the US Senate. Over beers after the meetings adjourned, Adams was asked how he was going to defeat the apparently formidable Slade Gorton, who had never lost a statewide election.  Simple, said the future Senator.  He could beat Slade because "Even his friends don't like him."

Sounds like Mitt's got the same problem.
