Washington (CNN) - A majority of Americans think that the Republicans will control Congress after Tuesday's midterm elections, but only a third say the country will be better off under a GOP takeover, according to a new national poll.
A CNN/Opinion Research Corporation survey released Sunday also indicates that a majority of registered voters say they are more likely to vote for a candidate who opposes President Barack Obama.
According to the poll, 51 percent of the public thinks the GOP will win back control of Congress on Tuesday, with 36 percent saying the Democrats will retain control.
Thirty-four percent of those questioned say the country will be better off if the Republicans win back Congress, with 28 percent saying the country will be worse off and 36 percent saying it won't make a difference.
"The belief that GOP control will make things better is highest among older voters and suburbanites, but even among those groups only four in ten say that Republicans will improve things in the country," says CNN Polling Director Keating Holland.
Thirty-nine percent of registered voters say they would be more likely to vote for a candidate who supports Obama, down from 54 percent a year ago, with 50 percent saying they would be more likely to vote for a candidate who opposes the president, up from 41 percent last October.
According to the poll, 46 percent of the public approves Obama's job performance, with 51 percent disapproving of how he's handling his duties. Fifty-five percent of Independent voters disapprove of the job the president's doing, with 39 percent saying they approve.
Fifty-six percent believe that Obama has not paid enough attention to the country's problems, and nearly half say he is too liberal. The public has more confidence in the Republicans than the Democrats on a number of issues, including the economy, health care, taxes, and the deficit.
The CNN/Opinion Research Corporation poll was conducted October 27-30, with 1,006 adult Americans - including 921 registered voters and 542 likely voters - questioned by telephone. The survey's overall sampling error is plus or minus three percentage points.
