Congressmen Targeted on Farm Bill

National Journal:

Heritage Action Fund is targeting three Republicans and a Democrat in agriculture-heavy districts over the farm bill with a round of radio ads, a spokesman tells Hotline.
The advertisements, complete with squealing pig sound effects, hit Reps. Rick Crawford (R-AR), Martha Roby (R-AL), Frank Lucas (R-OK) Mike McIntyre (D-NC) for pushing what Heritage calls a "food stamp bill" through Congress.
The members are "putting a tuxedo on a pig" by backing the bill, the ads say. Heritage Action will spend a total of $50,000 across the four districts; the ads begin running today, according to Heritage Action spokesman Dan Holler.

I would be curious to know why only these few members of Congress were targeted.  Are they the only rural members supporting the Farm Bill.  I doubt it, even though I'm pretty sure Jim Jordan will vote against it.  I would guess these are the only lawmakers representing rural districts that they narrowly won who are supporting the Farm Bill.  Probably, they are the only lawmakers representing rural districts that were narrowly won, since rural areas are generally very conservative.
