Democrats running in November's midterm US elections have made slight gains, according to a poll published on Tuesday, which nevertheless showed Republicans retaining a big lead ahead of next month's vote.
The Washington Post-ABC News poll showed Democrats cutting in half Republicans advantage from early September, when prospective voters were asked which party they were likely to cast ballots for during the November 2 congressional election.
Among likely voters, Republicans currently hold a 49 to 43 percent advantage over Democrats, the telephone poll of 1,002 randomly selected adults found.
The poll also showed Democrats making slight gains on the question of which party people trust to handle big issues, such as the economy and health care, and in their assessment about which party would do a better job in helping the middle class.
The poll also found that respondents trust Democrats more than Republicans to cope with the problems facing the country over the next year, by a narrow 41 to 39 percent margin.
And less than a month before the election, the survey also showed President Obama's approval rating rebounding to where it had been in July after hitting an all-time low a month ago.
The Washington Post reported that in some state races, Democratic candidates have taken the lead over or narrowed the advantage enjoyed by their Republican opponents.
The survey had a sampling error of plus or minus 3.5 percentage points.
