A New York Times article on Sen. Hillary Clinton's strategy heading into Indiana notes:
A senior Clinton aide said that she would tailor her message in Indiana to appeal to lower-income workers in the cities and to voters in rural areas and small towns.
The aide said Mrs. Clinton would continue to raise questions about Mr. Obama's readiness to face the many economic and national security challenges facing the country. He did not rule out running some version of an advertisement that the campaign ran in the final days of the Pennsylvania race showing images of the Great Depression, Pearl Harbor and Osama bin Laden and questioning Mr. Obama's fitness to lead in perilous times.
