Washington, Aug 10 - Both President Barack Obama and former president Bill Clinton brought 'just enormous intelligence' to the nation's top job, says the US Secretary of State Hillary Clinton comparing the way the two functioned.

'Well, I think both of them bring just enormous intelligence to the job,' she told CNN in an interview broadcast Sunday when asked what was the principal difference between how her husband ran the White House and how her one rime rival for Democratic presidential nomination was doing it.

'I mean, obviously, I know Bill much better. But I have seen in President Obama, as well, just an intelligence that is so compelling, to struggle with the difficult issues that are put before you,' Clinton said though the times are 'so different'.

In the White House, Bill Clinton was 'constantly seeking out information, always trying to figure out where to end up. And he does it in a very public way,' she said. 'I think that President Obama is very clear about the process that he wants to lead to his decision.

'I think, obviously, my husband made a lot of great decisions for our country, and I think that President Obama is doing the same.'

Her own relationship with Obama 'has really worked out better than anybody could have predicted,' Clinton said.

'I think our personal relationship has, you know, certainly deepened and broadened over the course of the last six and a half months. The time that we spend together, the difficult problems that we wrestle with.
