Gingrich: Trump can win only if he makes "real change"

“He has gotten himself to the edge of the mountain, he can get himself to the top of the mountain, but to do that he has to be willing to make real change,” said Mr. Gingrich, who emphasized that he was not criticizing Mr. Trump…

“He has to decide that the presidency is worth drilling into,” Mr. Gingrich said of Mr. Trump’s famously intractable style of behavior, and his relatively informal approach to debate preparation before facing Mrs. Clinton the first time.

“With the possible exception of Eisenhower, nobody in modern times has become president without making” major changes to their approach, he said.
