Bush leads Kerry by 7 points
By Susan Page, USA TODAY
WASHINGTON — President Bush widened his lead over John Kerry after a combative Republican National Convention deepened questions about the Democratic candidate's leadership, especially on terrorism. (Related link: Poll results)
As the campaign enters its last eight weeks, a USA TODAY/CNN/Gallup Poll taken Friday through Sunday shows Bush at 52%, Kerry at 45% and independent candidate Ralph Nader at 1% among likely voters. Before the convention, Bush led Kerry by 2 percentage points.
Among registered voters, Bush was at 48%, Kerry at 46% and Nader at 4%.
In actuality, no incumbant with a lead greater than four points at this stage has ever lost.
