There've been a trickle of reports like this over the past, few months.
Today's comes from The New York Times:
Aides and advisers to Mr. Romney, who acknowledge that he was never going to be the safest choice, privately say that they are troubled by Mr. Christie’s temper, calling it unsettling and out of step with Mr. Romney’s temperament.
(Indeed, some took it as a clear sign that he will not be picked when Ann Romney said in an interview that she expected her famously button-down husband to select a running mate with the “same personality type.”)
The most damning video, via TMZ, via July.
