Just two days after Mitt Romney announced Ryan as his running mate, Obama will highlight the Wisconsin congressman's opposition to the Farm Bill in a speech at a grassroots event in Council Bluffs, Iowa, according to excerpts. The Midwest is currently suffering from the worst drought in half a century, leaving a critical gap in livestock production in the country. Obama has repeatedly called on Congress to pass a farm bill that would provide disaster aid to more farmers and ranchers.
