'The media is jumping the gun by giving ticket to Obama', says fiery Clinton

Instead of attacking her rival Barack Obama she has focused on those who have written off her campaign.

A series of TV adverts running in Kentucky and Oregon blasts political pundits who say her bid for the White House is over.

On the attack: Hillary Clinton rallies her supporters on the campus of Western Kentucky University

Her campaign chiefs believe a media backlash helped boost her support in West Virginia where she trounced Mr Obama with a landslide.

Before the vote many pundits were dismissive of her chances and her staff attribute the success to voters disliking the way the media have already selected Mr Obama as the Democratic nominee.

Mrs Clinton hopes that similar triumphs in the remaining primaries will send a clear message to the "superdelegates" who are still uncommitted that she should have their vote.

The former first lady is expected to win comfortably in the Kentucky primary tomorrow.

Mr Obama is widely predicted to prevail in Oregon.

A TV advert being played in Oregon shows photographs of TV political pundits dismissing Mrs Clinton from the White House race.

Their voices are muted, and a narrator intones over their images: "In Washington, they talk about who's up and who's down. In Oregon, we care about what's right and what's wrong."

The US media, TV and print, has all but written off Mrs Clinton's hopes of being the first female president as Mr Obama has built a seemingly unassailable lead among delegates.

Campaign spokesman Mo Elleithee said: "People in the upcoming states don't want to be told that their voices don't count and essentially that's what they're being told.

"Well, the people of West Virginia didn't believe that and they sent a very strong message.

"Every time in this campaign that people have tried to call this race prematurely, the voters have rallied and sent a different message.

We saw it after Iowa. We saw it after South Carolina."
