Don't think there will ever be a smoking gun email or voicemail that will sink Christie on Bridgegate, but his staff trashing Wildstein for stuff going back to high school won't be forgotten. Coming after Christie said he was going to take charge, it was really petty, immature, and unnecessary. Not everybody has long commutes, but pretty much everyone went to high school and dredging up stuff 30+ years later is something nobody's going to condone. Up until then, Christie was a media darling, but that part of Bridgegate will stick. It's hard to predict what seemingly trivial events will sink people, but being out of touch in ways that are completely unrelatable are toxic. Poppa Bush and the scanner, Mitt and the car elevator, and Hillary's comments on wealth are prime examples.
