"Santorum...does lack Gingrich’s passion. Rather, he lacks Gingrich’s ability to project his passion. I have no doubt that Santorum has passion in his beliefs, but that doesn’t come across through television."

One could also read that as, "Santorum is more even-keeled, cooly analytical and more capable of controlling his passions."

“Santorum is more even-keeled, cooly analytical and more capable of controlling his passions.”
