President Barack Obama’s prime-time speech about his impending strategy for the war in Afghanistan drew more total viewers Tuesday night than recent high profile speeches about health care, according to Nielsen Media Research. All told, 40.8 million people on ten TV networks watched the president’s speech, up 27 percent from his health care address in September, and 65 percent from his health care press conference last July. The president’s biggest ratings, however, remain his February speech to a joint session of Congress about health care reform, which pulled in 52.4 million viewers.
