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.
