You can't savage the Mad Butcher, for heaven's sake. He's like everybody's favourite old Labrador - friendly, enthusiastic and willing to wag his tail at anyone.
Fenton's got a very short memory. Her former boss, Helen Clark, was a great mate of the Mad Butcher's and a regular at Mount Smart.
Even the current Labour leader, Phil Goff, was quick to distance himself from his junior MP's snarky sniping.
Fenton has since posted on the Labour blog, Red Alert, that while media kerfuffles don't usually bother her, in this case she recognised she'd gone too far and that she was sorry for her comments.
She also offered to buy the Mad Butcher a beer. She'll have to join a very long queue. His popularity made her mincemeat.
