Barack Obama gets strong popularity boost
US President Barack Obama received a significant popularity bounce from his party convention last week and now leads the White House race by a small but clear margin, polls indicated.
A CNN/ORC survey of likely voters released on Monday gave Obama 52 per cent of the vote compared with 46 per cent for Romney, who also fell behind last month in terms of fundraising, the first time he has trailed in the cash race since April.
A Gallup seven-day tracking poll also showed Obama ahead, with a five percentage point cushion, while another post-convention survey gave the Democratic incumbent a five per cent lead in the key battleground of Ohio.
The candidates were tied at 48 per cent support in the previous CNN/ORC poll, conducted before last week's three-day convention in Charlotte, North Carolina, at which Obama was formally nominated.
Hours before the results of the CNN/ORC poll were known, Romney's team was issuing a "State of the Race" bulletin that betrayed nerves in the campaign.
The first presidential debate between Obama and Romney in Denver, Colorado is now less than a month away on October 3.
