CLEVELAND, United States (AFP) - US President George W. Bush will head for Pennsylvania to deliver a major speech on terrorism and other crucial issues in a bid to bolster his reelection campaign after a heated debate between Vice President Dick Cheney and Democratic rival John Edwards.
Instant polls after the debate delivered a split verdict. ABC News gave Cheney a 43-35 percent edge over Edwards while Fox News had the North Carolina senator on top at 53-46 percent.
In addition to the war on terror, Bush was expected to speak about Iraq to showcase his national security record and compare it to that of Democratic rival John Kerry.
The race heated up late Tuesday as Cheney and Edwards clashed on Iraq, terrorism, and the economy in their only debate, trading frequently personal attacks 28 days before the November 2 election.
Facing the first question of the televised 90-minute exchange, Cheney said Saddam Hussein had "an established relationship with Al-Qaeda" and defiantly declared: "What we did in Iraq was exactly the right thing to do."
With millions of Americans watching, Edwards seized on Cheney's claim of links between Saddam and Osama bin Laden's network and charged: "Mr Vice President, you are still not being straight with the American people."
"There is no connection between the attacks of September 11 and Saddam Hussein," said Edwards. "And you've gone around the country suggesting that there is some connection. There is not."
Political analysts agree that vice presidential debates, which date back only to 1976, usually have little impact on the battle for the top job, but Tuesday's debate drew added significance from polls showing a tightening race.
But the absence of a clear, knock-out blow heightened expectations for the second televised face-off on Friday between Bush and Democratic rival John Kerry.
The White House also found itself besieged by new charges from a former top aide that it sent too few troops to Iraq and from fresh doubts about links between Saddam and Al-Qaeda -- a key justification for the March 2003 invasion.
Leading US newspapers emphasized the importance of the encounter but shied away from declaring either candidate the outright winner.
The New York Times noted in an editorial that Cheney "seemed tired and angry" while The Washington Post wondered if Edwards "has enough grounding in policy and politics" to perform the job he is running for.
Edwards, 51, hoped to build up Kerry's new momentum following what was widely seen as a victory over Bush in the first of their three televised debates last week.
Cheney, 63, tried to stop Kerry in his tracks by questioning his fitness to command the US-led global war on terrorism, while making the case that deadly chaos in Iraq will not derail progress towards elections planned for January.
"If I had it to recommend all over again, I would recommend exactly the same course of action," the vice president said defiantly. "I'm confident that, in fact, we'll get the job done."
A small smile rarely leaving his lips, Edwards assailed what he called the administration's misleading "rosy scenario" amid rising casualties among US troops there and stressed: "It's not just me that sees the mess in Iraq."
Echoing a charge from Kerry, Edwards accused the Bush administration of letting Al-Qaeda leader Osama bin Laden, "the man who masterminded the greatest mass murder and terrorist attack in American history," slip away.
"The senator has got his facts wrong," Cheney countered in his trademark baritone. "We've never let up on Osama bin Laden from day one. We've actively and aggressively pursued him."
There was little new in the content of the attacks and counter-attacks on Iraq, terrorism, or the economy, but the barbs were much more personal then when Kerry and Bush faced off last Thursday.
Edwards also accused the White House of focusing on Iraq at the expense of dealing with nuclear crises with Iran and North Korea.
Cheney linked Kerry's comment last week that US preemptive military action ought to pass a "global test" for legitimacy to what he said was the Democrat's belief three decades ago that US forces "should not be deployed without UN approval."
"A little tough talk in the midst of a campaign or as part of a presidential debate cannot obscure a record of 30 years of being on the wrong side of defense issues," the vice president added.
