About one in seven people who watched the speech changed their minds on Obama’s health care plan. “Going into the speech, a bare majority of his audience — 53 percent — favored his proposals. Immediately after the speech, that figure rose to 67 percent,” says CNN Polling Director Keating Holland. “But the real question is whether those conversions will last. Bill Clinton got similar numbers after his 1993 address to Congress, but five months later a majority of the country no longer supported his plan.”
