Thirty-eight percent said the Democratic convention made them less likely to vote for Obama, results indicated.
Since the convention, Obama has widened his lead in Gallup Daily tracking's seven-day rolling average from a 1 percentage point advantage of 47 percent to 46 percent, before the convention to a 5 percentage point advantage of 49 percent to 44 percent.
Obama's job approval rating also rose to 50 percent from 45 percent before the convention, the Princeton, N.J., polling agency reported.
Forty-three percent of Americans rated Obama's nomination acceptance speech Thursday as "excellent" or "good," better than the 38 percent who gave the same ratings to Mitt Romney's speech in Gallup's post-Republican convention poll.
Gallup said 56 percent of Americans rating former President Bill Clinton's speech positively, including 34 percent who said it was "excellent."
Results are based on nationwide telephone interviews conducted Friday and Saturday on the Gallup Daily tracking survey with 1,045 adults. The margin of error is 4 percentage points.
