Lobbyists for and against a federal sugar program are preparing for a bitter floor fight over the farm bill.

Industries that use sugar in their products are sending lobbyists to Capitol Hill to brief aides on legislation that would reform price and trade protections for the domestic crop.

Sugar producers are countering with a massive ad blitz that takes aim at “Big Candy’s Greed.”

Both sides in the subsidy debate say U.S. jobs — and the very survival of their industries — are at stake.

“We are not trying to put the [sugar] growers out of business. We are trying to have our own businesses survive,” said Liz Clark, the vice president of government affairs for the National Confectioners Association, which includes brands like Hershey, Mars Chocolate, Wrigley and Jelly Belly.
