At the end, President Bush appears to be enjoying his job more and letting his hair down. A case in point is a private fundraiser he attended July 29 in Cleveland for congressional Republicans. Our insider reports that the prez gave a breezy 40-minute tour of his time in office, calling it a "cool experience for Laura and I." He touched on many issues like his historic war on AIDS, especially in Africa, explaining that he pushed it in part because hopeless people have the potential to become terrorists. And he's willing to do whatever it takes—serious or tongue in cheek— to elect Sen. John McCain president. "If they asked him to endorse Barack Obama, he would do that," says our tipster of Bush's comments that go even further than his earlier joke about opposing McCain if it would help.
