Bush and his campaign team seized on the idea of Bush as a "strong wartime leader," though this was undermined by the increasingly-unpopular Iraq War. His conservative policies on tax cuts and several other issues appealed to many on the right, but Bush could also lay claim to some centrist achievements, including No Child Left Behind, Sarbanes-Oxley, and Medicare Part D. Fearing that he might hurt Bush's re-election chances, Cheney offered to step down from the ticket, but Bush refused this offer, and the two were re-nominated without opposition at the 2004 Republican National Convention. On the advice of pollster Matthew Dowd, who perceived a steady decline in the number of swing voters, the 2004 Bush campaign emphasized turning out conservative voters rather than the persuasion of moderates.
