Al Gore launched his national book tour Tuesday night with an event that seemed more like a campaign stop than a book signing.
Attendees wore "Gore 2008" buttons and some held signs that read "Re-elect Gore 2008." Gore, who lost the 2000 presidential election to Bush despite winning the popular vote, has said he is not running for the White House in 2008.
The former vice president joked with actor-satirist Harry Shearer during a discussion on "The Assault on Reason" that preceded a book signing at the Wilshire Theatre.
When asked about the timing of the book's release, Gore's response was drowned out by chants of "run, run, run."

In his book, Gore rips the Bush administration and laments what he describes as America's diminishing political discourse and eroding democracy.
During Tuesday's hour-long discussion, Gore said that despite a lack of evidence regarding weapons of mass destruction in Iraq, Congress and the media barely questioned the Bush administration.
"They were afraid of being branded unpatriotic," he said. "I'm troubled by the fact that we were so shockingly vulnerable to being manipulated."
Gore also charged that Bush did not ask questions during critical meetings on Osama bin Laden before the Sept. 11 terrorist attacks and on Hurricane Katrina before the storm made landfall.
"If there is a determined incuriosity, what that tells me is there is a belief that the way our country operates now, that there wasn't much fear on his part that he be held accountable by the news media or by the people or by Congress for not paying attention," he said.
The tour is one of several events in the coming weeks that will boost Gore's visibility - and inevitably invite questions about his political plans.
The former vice president, whose documentary "An Inconvenient Truth" won an Academy Award this year, is scheduled to headline the seven-continent "Live Earth" concerts in July to raise awareness on the threat of climate change. The concerts will mark the start of a multiyear campaign to fight global warming.
