WASHINGTON, Oct. 16 On an overcast Friday morning last month, White House aides ushered an influential group of conservative radio hosts into the Oval Office for a private audience with the president.
For an hour and a half, Mr. Bush discussed his case for the war in Iraq, his immigration proposals and even the personality of his Scottish terrier Barney, who scratched on the door during the session until the president relented and let him into the office, according to several hosts who attended.
The meeting, which was not announced on the presidents public schedule, was part of an intensive Republican Party campaign to reclaim and re-energize a crucial army of supporters that is not as likely to walk in lockstep with the White House as it has in the past.
Conservative radio hosts are breaking with the Republican leadership in ways not seen in at least a decade, and certainly not since Rush Limbaughs forceful advocacy of the party in 1994 spawned a new generation of stars, said Michael Harrison, publisher of the industrys lead trade publication, Talkers.
Disgruntlement can now be found not only among the more flamboyant radio voices, like Michael Savage, who raged against Mr. Bushs proposals on immigration and other issues, but also among more mainstream hosts, like Laura Ingraham, who told her listeners in the wake of the scandal involving former Representative Mark Foley and under-age Congressional pages, You have to ask yourself, the people who are in positions of power now in the Republican Party, are they able to credibly articulate the conservative agenda to the American people to rally the base, to rally the country?
Such questions, coming from such quarters, have created yet another challenge for the White House and the central party leadership as they work to steer Republicans to victory next month in the face of low approval ratings and dissatisfaction among the party faithful.
Strategists on both sides agree that the partys greatest hope for holding control of Congress now rests with its ability to get core Republicans to vote, and that talk radio, which reaches millions of them, is crucial to the task.
Democratic strategists say talk radio remains a fearsome Republican advocacy force for which they have little direct answer. (Air America, which features liberal hosts, including Al Franken, filed for Chapter 11 bankruptcy last week.) The top two rated conservative hosts, Mr. Limbaugh and Sean Hannity, have done more than their part to rally their listeners this year, especially during the Foley scandal, to the great relief of Republican Party officials. And even those critical of Mr. Bush or the party on specific issues still consider themselves major supporters in general, with perhaps the exception of Mr. Savage.
But Mr. Savage is the third most popular host in the nation, with at least eight million listeners weekly, according to Talkers. And the Democrats have watched happily as he and others have at times sent reverberations of conservative frustration into what they often call the Republican echo chamber.
The challenge now falls to party strategists to persuade the hosts to overcome the frustrations of many hard-core listeners over issues like spending and border security without alienating them.
When conservatives are agitated at the president, radio hosts feel pressured to stand with the conservatives against the president to prove their independence, said Tim Graham, an analyst at the Media Research Center, a conservative news monitoring group. But, Mr. Graham said, realizing what life would be like if we lost the House is concentrating peoples minds.
The White House and the Republican National Committee are hammering home that point in interviews, talking-point bulletins and a healthy dollop of pomp that only a White House can provide.
The effort will peak on Oct. 24, when the administration will hold something of a talk-radio summit meeting, inviting dozens of hosts to set up booths on the White House grounds, where top cabinet officials are expected to sit for interviews.
The party chairman, Ken Mehlman, has already been working overtime on the talk radio circuit. From Wednesday to Friday of last week, he was interviewed a total of 20 times in Missouri, Tennessee and Ohio, promoting party stances on tax cuts and terrorism.
But, several hosts said, the most telling development so far this year was the White House decision to invite some of the most popular hosts to the Oval Office for off-the-record time with the president.
Kevin Sullivan, the White House communications director, said the meeting was among the latest examples of the administrations effort to put Mr. Bush in front of more news media as his own best spokesman. The president also gave interviews recently to several television anchors and held an Oval Office chat with a group of conservative writers.
And Mr. Bush granted an on-camera interview to Bill OReilly of the Fox News Channel. The first of three parts ran Monday night.
Still, officials said, the meeting with the radio hosts gave Mr. Bush a chance to speak intimately with a group that reaches an overwhelmingly Republican audience of 30 million people per week.
