NEW ORLEANS (AP) — Republican U.S. Senate candidate John Kennedy changed his approach Wednesday, focusing on the country’s economic crisis rather than presidential politics as he faced off with Democratic incumbent U.S. Sen. Mary Landrieu in the third debate of the Senate race. The tactical switch came amid reports that national Republicans who had poured millions of dollars into TV advertising on Kennedy’s behalf were pulling out of the state’s ad race next week and leaving the GOP state treasurer largely on his own as he tries to keep Landrieu from a third term. In past debates Kennedy opened by aligning himself with Republican presidential contender John McCain, but on Wednesday he described his ideas for re-establishing economic stability.—-Contact The Daily Reveille’s news staff at [email protected]
