CRAWFORD, TXFit, trim, confident in his power base, and above all well-rested following a four-week, three-day vacation at his Crawford ranch, President Bush is currently in the prime of his presidential form, pundits say. 'Our leader is pumped and primed following his well-earned time off from the economy and the war in Iraq,' commentator Sean Hannity said on his radio show Monday. 'He is ready to do whatever this nation requires of himdelegating responsibility to capable people, winning a war, rallying citizens around him in the aftermath of a disasterwhatever may come.' Bush had originally planned to extend his vacation, as eminently qualified FEMA head Michael Brown is assumed to be taking charge of a routine hurricane in New Orleans.
