The Pew Research Center’s latest voters poll found support for the Democrat candidate had grown to 52 per cent of voters, compared to 38 per cent for his Republican rival.
A Pew poll at the beginning of October showed a seven-point gap between the two. The new poll was conducted from Oct16-19 among 2,599 people and has a 2.5 point margin of error.
It comes after a Wall Street Journal/NBC News poll of 1,159 people showed Mr Obama ahead of Mr McCain by 10 points, up from six points two weeks ago.
Pew said Mr Obama’s surging popularity was mostly due to voters’ dwindling confidence in Mr McCain, as witnessed after each of the candidates’ three TV debates.
The Pew poll found voters trusted Mr Obama over Mr McCain on all issues including Iraq and the war on terror.
On who is best suited to fix the economic crisis, Mr Obama was picked by an overwhelming 53 percent of respondents, against 32 per cent for Mr McCain.
Forty-one per cent of voters thought Mr McCain showed bad judgement in the choices he made, compared to only 29 per cent for Mr Obama.
The age factor was also a concern for voters, with 34 per cent of respondents saying Mr McCain was too old to be president – at 72, he would become the oldest president elected to a first term in office.
As far as Mr McCain’s choice of running mate, Pew found voters were more divided: 49 per cent disapproved of Alaska Governor Sarah Palin, 44 per cent approved her.
However, there was one silver lining in the Pew poll for Mr McCain: 23 per cent of voters said they were still undecided. The Telegraph
