White House race enters high gear

Candidates often see a surge in popularity after the party conventions

The US presidential rivals have begun campaigning in earnest, as a new opinion poll put Republican John McCain ahead of Democrat Barack Obama.

Fresh from being nominated at their party conventions, the two men are now gearing up for the 4 November poll.

A USA Today-Gallup poll put Mr McCain ahead for the first time in months.

Candidates often see a bounce in the polls after the conventions but Mr McCain’s choice of Sarah Palin as running mate is being seen as key.

Mr McCain has tried to strike a balance between distancing himself from an unpopular presidency and rallying the party’s conservative base.

Mrs Palin wowed the Republican convention crowd with her speech, helping to re-energize his campaign.

Major test

Mr McCain said that “the electricity has been incredible” at rallies ever since he invited the Alaskan governor to join his ticket.

“She has excited people all over the country. I would love to say it was all because of the charisma of John McCain, but it is not,” he told CBS on Sunday.

Mrs Palin will face a major test this week when she gives her first nationally televised interview, following intense media scrutiny over her personal life and credentials for the ticket.

The USA Today-Gallup poll, which was released on Sunday, showed Mr McCain leading Mr Obama by four percentage points, 50 to 46.

A USA Today poll taken before the Republican convention showed Mr McCain trailing Mr Obama by seven points.

The latest poll had a margin of error of plus or minus three percentage points.

The results of a Reuters/Zogby poll, also released over the weekend, gave Mr McCain the edge, with 50 percentage points to 46.

The Rasmussen Reports daily Presidential Tracking Poll showed John McCain with a one-point lead.

Mr McCain and Mrs Palin are scheduled to be in Missouri on Monday.

Mr Obama is campaigning in the crucial swing state of Michigan. His vice-president, Joe Biden, was appearing in Wisconsin and Iowa, while Hillary Clinton is on the campaign trail in Florida.

Despite the frenetic pace of the presidential race, the candidates will stop campaigning on Thursday to appear together in New York on the anniversary of the 11 September 2001 attacks.

They said they would put aside politics to honour the memory of the nearly 3,000 people who died.

Obama set to reveal running-mate

Speculation has been rife about who will share Mr Obama’s platform

US Democratic presidential hopeful Barack Obama is expected to reveal his choice of vice-presidential running mate within hours.

He has told journalists he has made his decision, which will be revealed by text message to the party’s senators and supporters, and journalists.

Democrats gather for their party convention in Denver on Monday.

Mr Obama and his running mate are set to make their first campaign appearance together in Illinois, on Saturday.

“I’ve made the selection, that’s all you’re gonna get,” Mr Obama told reporters while campaigning in Virginia on Thursday.

Text alert

In an interview with USA Today newspaper, the Illinois senator said he had selected a running mate who was independent and would challenge him in the White House.

He added that he had opted for someone who would help him strengthen the economy, and was also ready to act as president.

But Mr Obama gave no clue as to whether he had notified his preferred running mate yet.

It is possible the Obama camp might keep the name of the vice-presidential selection a secret until just before the appearance in Springfield on Saturday but, realistically, that seems unlikely, says the BBC’s North America editor, Justin Webb.

The expectation is that during the course of Friday a text message will be received by those who have signed up for it, revealing the name.

Surprise in store?

The conventional wisdom is that vice-presidential candidates do not swing elections, our editor reports.

But Mr Obama’s choice is interesting because it will reveal a little more about the style of the man and how willing he is to be adventurous.

Most commentators believe he will play it safe, opting for a governor, perhaps Tim Kaine of Virginia, or a political veteran like Senator Joe Biden.

Some Democrats are hoping he has a surprise up his sleeve – a Hillary Clinton or an Al Gore.

Mr Obama’s rival, Republican presidential hopeful John McCain, has reportedly not settled on a running mate.

Minnesota Governor Tim Pawlenty and former Massachusetts governor Mitt Romney are reported to be under serious consideration for the role.
