WASHINGTON - The passage of the landmark healthcare reform had no apparent effect on U.S. President Barack Obama's job-approval rating, poll results released Friday indicate. The Harris Poll found 41 percent of Americans give Obama a thumbs-up on the job he is doing and 59 percent a thumbs-down. That's the same as last month. Congress fared better this month, with 84 percent of Americans giving it negative ratings compared with 90 percent in March. Along party lines, lawmakers got positive ratings from 28 percent of Democrats, 11 percent of Independents and 4 percent of Republicans. Republicans remain overwhelmingly negative (91 percent) about the Democratic president, as are 64 percent of Independents and 30 percent of Democrats, the survey showed. Along generational lines, 45 percent of Baby Boomers (ages 46-64) and 43 percent of Echo Boomers (ages 18-33) give Obama positive ratings, compared with 34 percent of Generation Xers (34-45) and 36 percent of Matures (65 and older). Sixty-two percent of women gave Obama negative marks, compared with 56 percent of men. The survey also revealed Americans are more optimistic about their country, with 39 percent saying things are going in the right direction, up from 33 percent in March. Harris Interactive surveyed 2,755 adults April 12-19. Because the respondents were selected from among people who have agreed to participate in the firm's surveys, no margin of error could be calculated, Harris Interactive said.
