This excerpt from Double Down rattles off some of them:

The [Romney campaign's VP] vetters were stunned by the garish controversies lurking in the shadows of his record. There was a 2010 Department of Justice inspector general’s investigation of Christie’s spending patterns in his job prior to the governorship, which criticized him for being “the U.S. attorney who most often exceeded the government [travel expense] rate without adequate NJ Governor Chris Christie Holds Town Hall Meetingjustification” and for offering “insufficient, inaccurate, or no justification” for stays at swank hotels like the Four Seasons.

There was the fact that Christie worked as a lobbyist on behalf of the Securities Industry Association at a time when Bernie Madoff was a senior SIA official—and sought an exemption from New Jersey’s Consumer Fraud Act. There was Christie’s decision to steer hefty government contracts to donors and political allies like former Attorney General John Ashcroft, which sparked a congressional hearing. There was a defamation lawsuit brought against Christie arising out of his successful 1994 run to oust an incumbent in a local Garden State race.

Then there was Todd Christie, the Governor’s brother, who in 2008 agreed to a settlement of civil charges by the Securities and Exchange Commission in which he acknowledged making “hundreds of trades in which customers had been systematically overcharged.” (Todd also oversaw a family foundation whose activities and purpose raised eyebrows among the vetters.) And all that was on top of a litany of glaring matters that sparked concern on Myers’ team: Christie’s other lobbying clients, his investments overseas, the YouTube clips that helped make him a star but might call into doubt his presidential temperament, and the status of his health.

I think using his brother against him is de trop. But it’s always worth remembering that many many candidates who seem extremely promising on paper can come a-cropper – especially if they display the kind of aggressive cockiness of the New Jersey governor.
