In an interview with the Indianapolis Star, Daniels offered suggestions to Romney:
"Go ahead and have the confidence in the voters to explain the fix we're in and then tell them with some specificity what we can do to get out of it in a way that's good for everybody," Daniels said. "Explain those things from the standpoint of the young and poor -- those who haven't achieved the dream yet."
The Republican governor said: "You have to campaign to govern, not just to win. ... Spend the precious time and dollars explaining what's at stake and a constructive program to make life better. And, as I say, look at everything through the lens of folks who have yet to achieve."
Daniels paused, the Star said, then added, "Romney doesn't talk that way."
CBS News said President Barack Obama's political strategist, referring to Daniels' comments, said in a Twitter post Thursday: "Even Mitt's friends are warning him. Grinding negativism has its limits."
Daniels said political candidates should make plain how their policies would help those struggling.
"It's not complicated," Daniels said. "But for some reason sometimes candidates just miss that."
