FILE - In this March 10, 2006 file photo, Ohio coal miners head into the mine for a shift inside the Hopedale Mine near Cadiz, Ohio. An election-year bill that would protect health-care and pension benefits for more than 100,000 retired coal miners is dividing coal-state Republicans. Thousands of miners are expected to gather at the Capitol to push for the measure, which they describe as life-saving and fulfilling a promise the government made in 1946.
