Here's Gov. Romney position paper on agriculture (reached via Chris Clayton)--I searched for "insurance" and came up empty, searched for "payment" and came up empty. He wants "energy independence", "rational regulation" "new markets" and "reasonable taxation",
In fairness I should note I didn't check Obama's campaign, but by necessity he's been a bit more specific. And at least Mitt doesn't lump USDA in with Big Bird.
