A CNN/ORC Poll also released Monday morning shows Trump with a 3-point lead over Clinton, 48 percent to 45 percent, after a 6-point post-convention boost for the businessman.

Seventy-four percent of those polled by CBS said they watched the GOP convention in Cleveland, with most saying it improved their perception of Trump. Fifty percent said the event made them feel better about Trump, and 36 percent said it hurt their view of the billionaire.

Many voters still have concerns about Trump, however, with 58 percent saying he is unprepared for the presidency.

Fifty-six percent said he is not honest; 61 percent said he lacks the temperament and personality for the nation’s highest office.

Half of voters view Clinton as prepared for the White House, meanwhile, with the same proportion calling her a strong leader.

Fifty percent say she also has the temperament for the Oval Office, but 66 percent say she is not trustworthy.

CBS News conducted its latest sampling of 1,118 registered voters via cellphone and landline telephone interviews July 22–24. It has a 4 percentage point margin of error.
