Debate over foreign policy and how best to wage the war on terror continues to dominate the early stage of the 2008 U.S. presidential election campaign.  VOA National correspondent Jim Malone has more from Washington.

In the latest Democratic candidates forum in Chicago, Senators Chris Dodd of Connecticut and Hillary Clinton of New York criticized Obama's recent statements on Pakistan.

"You can think big but remember, you should not always say everything you think if you are running for president, because it can have consequences across the world and we do not need that right now," she said.

Despite the criticism from his fellow Democrats, Senator Obama did not back down and said his critics should be subject to similar scrutiny for initially supporting the war in Iraq, a war that Obama opposed before he was elected to the Senate.

Clinton supporters argue that Obama's recent comments on Pakistan and other foreign policy issues reinforce their contention that he does not have the experience to be president.

Obama supporters counter that their candidate offers a fresh direction for U.S. foreign policy in the wake of an unpopular war in Iraq.

"I think what people are going to be talking about is, 'is Obama slapping down the criticism from Chris Dodd and Hillary Clinton by again pointing out that he opposed the war and they voted for it and who are they to kind of claim some sort of high ground in terms of foreign policy judgment," he explained.

The Republican presidential contenders have taken note of the debate unfolding among the Democrats.

Former Massachusetts Governor Mitt Romney criticized Obama during a recent Republican debate in Iowa.

"I had to laugh at what I saw Barack Obama do," he said.  "I mean, in one week he went from saying he was going to sit down for tea with our enemies, but then he is going to bomb our allies.  He has gone from [former anti-Vietnam war protester] Jane Fonda to Doctor Strangelove in one week!"

But not all the Republicans were critical.  Former New York City Mayor Rudy Giuliani is pinning his White House hopes on convincing voters that he is the candidate best able to lead the war on terror.

Hillary Clinton leads the Democratic field and recent polls suggest she is expanding her lead over Senator Obama.  However, polls in the early contest states of Iowa, New Hampshire and South Carolina show a close race among Clinton, Obama and former North Carolina Senator John Edwards.

Rudy Giuliani leads on the Republican side, but by a smaller margin over former Senator Fred Thompson of Tennessee, Senator John McCain of Arizona and Mitt Romney.

Romney, however, leads among Republican voters in the early voting states of Iowa and New Hampshire.

Fred Thompson is expected to officially enter the race in September.
