President Bush’s approval rating has fallen to 45%, the lowest point of his presidency. This according to a new USA TODAY/CNN/Gallup Poll. It found the largest drop for Bush came among men, self-described conservatives and churchgoers. Independent political analysts said the drop may reflect opposition to the White House and Congress intervening in the Terri Schiavo matter. A USA TODAY/CNN/Gallup Poll last weekend found that 61% would have a spouse’s feeding tube removed under similar circumstances.
