New York: Former American president Bill Clinton's much-awaited autobiography in which he gives an account of his affair with intern Monica Lewinsky and the subsequent personal moral dilemma went on sale today in book stores across the United States with thousands of his fans queuing up to buy copies of it.

The 957-page book 'My life' is expected to become an easy best seller as thousands of people lined-up for several hours in book shops to buy it.

At a venue, about one thousand people held a party to celebrate the occasion even as the conservative groups prepared rebuttals and tried to take initiative out of hands of the Democrats.

The book encouraged Democrats who believe it would give a boost to the election campaign of their Presidential candidate John Kerry but Republicans expressed the view that it could overshadow the Kerry's campaign to the advantage of President George W Bush.

Analysts were reserving their judgement and currently giving both view points. They want the issue to play out for the next few days before making any call.

As Clinton appeared on CBS television on Sunday night to promote his book, a conservative lobbying group 'Citizens United' took out advertisements holding him responsible for failing to prevent the September 11 attacks.

It also listed the terrorist attacks abroad during his presidency.

However, the Conservatives' main weapon might be the issue of morality and they have been indirectly referring to it by contending that Bush had restored the dignity of the Oval Office in apparent reference to Clinton's episodes with Monica Lewinsky.

"I have found that the best way to get a rousing response from a crowd is to say that whatever disagreements you may have with President Bush on one issue or another, nobody can argue that he hasn't restored honour to the White house," Gary L Bauer, chairman of the organisation 'American Values' was quoted as saying by the 'New York Times'.

"I think there is a reason that the Kerry people were not all that excited about this book coming out now."

Grover G Norquist, a conservative strategist and Chairman of Americans for Tax Reform, has been quoted as saying that after the terrorist attacks of September 11 the Bush Administration had failed to blame the Clinton administration enough, thus leaving Bush vulnerable to criticism from the federal commission investigating the attacks.

Now, Norquist said, the discussion of Clinton's book offered Republicans another chance to blame him.

Kerry said he considered Clinton an asset but Conservative strategists believe that constant reminder of 'Clinton years' would help Bush.
