Trump Speaks After Receiving GOP Nomination: 'We Have to Go All the Way'

On "Hannity" tonight, Frank Luntz spoke to a focus group of undecided voters about the Republican National Convention and the most impressive speaker they saw tonight: Donald Trump Jr.

They described the son of the Republican presidential nominee as very sincere, charismatic, authentic, articulate and genuine.

"The father should take lessons from the son," one man said. "He didn't tear anybody down."

Several members said they wish that Trump Sr. was more coolheaded and less controversial like Trump Jr.

They acknowledged, however, that a great child is testament to great parenting.

"If Donald Trump would act at home the way that he acts on television, his son wouldn't be the way that he is now," one participant explained.

When Luntz asked if they would like to see Donald Trump Jr. run for office someday, 16 out of 19 members of the focus group responded favorably.
