Liberal "discretion."

Via Glenn Reynolds:  From Power Line.

“Here in Minnesota, we are experiencing a remarkable instance of how discreet liberals can be when it comes to a candidate’s personal life. Mark Dayton is running for Governor of this state, and his history of mental illness and substance abuse is hiding in plain sight–he has freely acknowledged these problems to almost-complete strangers, yet Minnesota’s reporters and editors have carefully avoided confusing the voters with information that might not reflect well on a Democrat. Somehow one senses a pattern here.”

Sort of like the media's determination to hide John Edwards' cheating on his cancer stricken wife until ... and even past the time ... the pictures were all over the tabloids.
