RICHMOND, Va. (AP) -Sen. John McCain of Arizona will appear with Sen. George Allen in Norfolk on Aug. 16, and former New York Mayor Rudolph Giuliani will join Allen in Hampton Roads on Aug. 30. to help Allen's re-election campaign.

Allen, McCain and Giuliani have all been mentioned as possible presidential candidates in 2008.

President Bush, meantime, will be the main attraction at an Allen fundraiser Aug. 23 at the Fairfax County home of former Republican National Committee chairman Ed Gillespie.

A spokeswoman for Allen's opponent, Democrat Jim Webb, made light of the private nature of the incumbent's meeting with Bush, whose job approval ratings have been falling.

"If the president is so welcome in Virginia, why doesn't he go have a couple of campaign events with him -- especially in northern Virginia, since it's so easy to pop over the river," Webb spokeswoman Kristian Denny Todd said Wednesday.

Allen campaign manager Dick Wadhams countered that Webb "knows very well that most campaign fundraisers on both sides are not public events."

Wadhams noted that Webb was in California on Wednesday "raising money with his Hollywood friends, and I doubt those meetings are public."

Denny Todd confirmed that Webb, a former Reagan administration Navy secretary turned novelist and moviemaker, was on a West Coast fundraising trip that includes meetings with some show business executives but "no actors."

Wadhams dismissed the Webb campaign's criticism as "background noise to what's really going on right now, and that's the Webb campaign sucking air financially."

Allen began July with $6.6 million on hand to Webb's $424,245, according to Federal Election Commission reports.

The Webb campaign has been emphasizing Allen's heavy support of the Bush White House agenda in hopes that the president's unpopularity will rub off on the senator. A Mason-Dixon Polling and Research Inc. survey in Virginia last month showed Bush with a 43 percent approval rating, down from 58 percent in October 2004.
