Earlier today, Democratic Secretary of Agriculture candidate Denise O'Brien held a conference call with supporters and members of Farm Bureau who are objecting to a letter from the Farm Bureau's PAC supporting Republican Bill Northey while attacking O'Brien. A full press release from the O'Brien campaign is below the fold, but let's put it this way: The President of the Farm Bureau has never taken such steps in attacking the opponent of the candidate it has endorsed in a letter to all members. Radio Iowa and the Register tackle the issue here and here, respectively. Essentially, Denise is getting smeared as a "progressive" and as an "activist" and is accused of being against "modern farming techniques."
