Carly Fiorina, previously CEO of HP, is back in the spotlight – this time as an advocate for John McCain, who is expected to become the Republican presidential nominee. 

Fiorina will travel around the US telling voters about the Republican economic principles and will urge people to make the effort to vote.
McCain is rapidly becoming surrounded by high-tech advisers: Cisco CEO John Chamers is the campaign's finance co-chairman and advises McCain on technology.
The campaign's economic message will help to address US economic fears.
Since leaving HP in 2005, Fiorina has been active in politics, having worked with Calfornia governor Arnold Schwarzenegger and been mentioned as a possible governor herself – or even as running mate for McCain.
