After gauging the harsh reaction from Democrats and Republicans alike to Sen. Zell Miller’s keynote address at the Republican National Convention, the Bush campaign — led by the first lady — backed away Thursday from Miller’s savage attack on Democratic presidential nominee John Kerry, insisting that the estranged Democrat was speaking only for himself.

Late Thursday, Miller and his wife were removed from the list of dignitaries who would be sitting in the first family’s box during the president’s acceptance speech later in the evening. Scott Stanzel, a spokesman for the Bush campaign, said Miller was not in the box because the campaign had scheduled him to do too many television interviews.

There was no explanation, however, for why Miller would be giving multiple interviews during Bush’s acceptance speech, or what channels would snub the president in favor of Miller. Nor was it made clear why Miller’s wife also was not allowed to take her place in the president’s box 24 hours after his deeply personal denunciation of his own party’s nominee.

The change was made only a few hours after Laura Bush, asked about Miller’s speech, said in an interview with NBC News that “I don’t know that we share that point of view.” Aides to President Bush and his campaign said.
