The race to become candidate for president of the USA can change overnight - and few people know that better than Howard Dean.

He ran to be the Democratic candidate in 2004, and led the field for months, but crashed out of the contest that went on to be won by John Kerry, who was then beaten to the White House by George Bush.

Daily Politics reporter Ellie Price met Mr Dean who has been on a trip to London and asked him about standing as a candidate.
