MANCHESTER, N.H.--With less than four days before the voting booths open here in the Granite State, all five major Democratic candidates are facing an invisible but formidable opponent.

The Undecided.

With polls showing anywhere from a third to half of all New Hampshire voters still unsure for whom they will vote on Tuesday, candidates are wooing the unusually large group that just can't make up its mind.

Many voters complain that the choice that has been left to them--between five major presidential candidates and more than two dozen minor ones--is no choice at all.

"Most of us don't know what we're really going to do," said bookkeepr Aldona Hoppe, 58, as she sat doing her knitting in the Notre Dame College gymnasium before a conference on the savings and loan crisis Saturday.

"We're sort of sick and tired of the whole bunch," she said.

And Laverne Cassidy, the 54-year old owner of Sweet Food Market in Salem, sitting in her empty convenience store, spoke of her own dissatisfaction.

"Everybody's just talking and saying nothing--which is typical of politicians," Cassidy said.

The rise of former Massachusetts Sen. Paul E. Tsongas over Arkansas Gov. Bill Clinton in the polls this week reflects the fluidity of New Hampshire Democrats' votes. But those polled have also said they are still unclear on who they will choose on Tuesday.

In 1998, widely perceived public apathy caused the media to dub the Democratic candidates "the seven dwarfs." This year, with the recession having decimated the state's economy, New Hampshire voters are not apathetic--they are frustrated.

Roger R. Plamondon, 40, used to work in manufacturing. After an on the-job injury in 1987, he was laid off and was forced to work other jobs. Currently, he is working at a hotel front deskin Laconia for one-third his former salary andstudying to be a paralegal on the side.

"This is the worst I've ever seen it," said thefather of three, referring to the economy.

Voters interviewed emphasized the need for acandidate who will save the nation from therecession.

"Even with the country in a depression--that'swhat this is--it doesn't seem like people see muchof a choice on either side," said Joe Perrota, 58,sipping coffee at the front counter of Pattavina'sFamily Restaurant in Salem.

But Perrota, a self-employed photographer, saidhe thinks the media is as much to blame as anyonefor the public's frustration.

"It seem it's always something negative. Theydon't express anything on the positives," Perrotasaid.
