"Bush screamed at the G.O.P. strategist, "You can leave and you can take the rest of these lily-livered motherfuckers with you!"

A growing number of Republican leaders, party strategists and political professional now privately tell President George W. Bush that his presidency "is effectively over" unless he fires embattled White House advisor Karl Rove, apologizes to the American people for misleading the country into war and revamps his administration from top to bottom.

"The only show of unity we have now in the Republican Party is the belief that the President has failed the party, the American people and the presidency," says a longtime, and angry, GOP strategist.

With the public face of support for Bush eroding daily from even diehard Republicans, the President faces mounting anger from within his party over the path that may well lead to loss of control of Congress in the 2006 midterm elections and the White House in 2008.

"This presidency is in trouble," says a senior White House aide.
