Though the war is not over, Bush's success in swiftly ousting the Iraqi president's regime could make him a force to be reckoned with in Washington in coming months. He will try to score victories on such issues as tax cuts, education and health-care initiatives, and the confirmation of conservative judicial nominees. Some of those items have stalled on Capitol Hill as the war has absorbed Bush's time and attention.
"There will be a peace dividend. There'll be huzzahs, and this president, I think, is smart enough to cash in on it," said Tom Korologos, a veteran Republican lobbyist. "There's a lot of reserve political cash in that vault that he can draw on for his domestic program."
On Friday, Bush signaled the priority he would assign to issues vital to Americans at home. He noted, in particular, the need to boost the ailing economy and to reform Medicare. "There's a lot on my agenda," the president said at the National Naval Medical Center in Bethesda, where he visited sailors and Marines wounded in the war.
Bush's advisers play down any notion that he neglected domestic matters before and during the war or that he is counting on a postwar boost to help push through his agenda.
"There has been no cessation in domestic energy," a senior administration official said. "We're not at ease because we're at war. It's just a little below the radar."
Bush, this official said, has "always been able to engage the Congress and get things done on the domestic side."
Still, Bush's advisers concede that the demise of Hussein's regime will inevitably renew a focus on such home-front issues as the economy, health care and education.
"I look for us to turn our attentions -- rightfully so -- to the domestic side" after the war, the administration official said.
The president and his top political adviser, Karl Rove, have shown a willingness and ability to use the full weight of the White House to back legislative initiatives and help elect Republicans. Bush succeeded, for example, in pushing through an across-the-board tax cut in 2001 and in helping Republicans score sweeping victories in last year's congressional elections.
"I expect that he'll expend his excess political capital at the end of the war," said Sheila Tate, a former Republican spokeswoman. "It's his inclination to do so, and he's not been afraid to before. He'll push for everything he can get."
In the latest Newsweek poll, 71 percent of respondents said they approved of Bush's handling of his job, up 18 percentage points from a month ago, before the war began. The new poll was conducted Thursday and Friday; the margin of error was 3 percentage points.
There is still some risk that a persistent humanitarian crisis or lawlessness in Iraq could cloud the perception of U.S. success and limit a rise in Bush's popularity. And some Republicans concede that as the war subsides, Democrats could become bolder about criticizing Bush and challenging his priorities. The weak economy Bush is presiding over could also fall under more scrutiny.
"The president will have some good will coming off of what I hope will be a successful result in Iraq," said Rep. Rob Portman of Ohio, a Republican leader who is close to the White House. The lesson of 1991 is "you cannot warehouse good will and support -- we need to harness it."
Republican leaders know they will need more than a popular president to push through top agenda items. Victory in Iraq, they say, will shift attention back to domestic issues on which Democrats think Bush might be vulnerable and could motivate his opponents to work harder to derail his agenda.
The White House and Republican leaders have been working to avoid repeating the mistakes of Bush's father. With bombs falling and bullets flying, they have continued to push the Bush economic-growth package over 10 years -- as well as an energy-policy overhaul, his "faith-based" initiative and the contentious nomination of Judge Miguel A. Estrada to a federal district court.
But the effort has suffered severe setbacks, and some Bush allies say he will have to make up a substantial amount of ground to recover.
The president has seen his growth package jeopardized as Republican moderates have joined Democrats to insist that Congress approve no more than $350 billion in tax cuts. Before that, eight Republicans joined Democrats to oppose oil and gas drilling in Alaska's Arctic National Wildlife Refuge, a major part of Bush's energy policy.
