It's valid to ask how Sen. Judd Gregg dropping out is in anyway Obama's fault.
Of course, the article MEM is "responding" to didn't allege it was Obama's fault as much as it was the fault of his chief of staff.
But, for the sake of argument, it should be noted that part of the "vetting" process is giving a potential job candidate a full and fair picture of the duties of the position and what the President/employer expects. It seems as if that didn't happen here, resulting in Gregg deciding to turn the job down as it became clear the President and he didn't see eye to eye on the issues facing the department and/or the the positions to be taken by it.
I tend to place blame with the boss I suppose but either way Sen. Judd Gregg dropping out was really up to him. It was a given that Gregg as a conservative republican wasn't going to see eye to eye on the issues but he was the one who said he wanted and could do the job at first. There are many valid criticisms when it comes to Obama's other appointments but this one just seems to be a reach.
