http://news.independent.co.uk/world/americas/story.jsp?story=481007The Democratic candidate Howard Dean is fighting hard to retain the narrow lead he holds in next week's crucial and increasingly bitter-fought Iowa caucuses - launching a series of attacks on his opponents and reiterating his claim to be the only genuine alternative to President George Bush.
Singling out Mr Kerry, Mr Edwards and Mr Gephardt by name for their support for the decision to invade Iraq, he added: "I want you to remember a week from tonight when you caucus who stood up against that war when no one else would."
In recent weeks, Mr Dean's status as Democratic front-runner has led him and his policies to be placed under unprecedented scrutiny by political pundits and the US media. This has led to a number of claims that he has shifted his position on key issues and, potentially much more damaging, accusations that he has made a series of "gaffes". These have been seized on by his opponents and former general Wesley Clark, who is not taking part in the Iowa contest, has moved into a close second in the polls for the New Hampshire primary on 27 January.
There is more than a suggestion, however, that the flurry of stories pointing to a "shakiness" in Mr Dean's campaign and claims that support for him is decreasing, are based less on real evidence rather than a concerted effort by some Democrats and by Republicans to do everything and anything to stop him becoming the party's candidate.
