Brooks was one of several panelists on NBC's "Meet The Press" roundtable, which dove into some data surrounding Romney's popularity.
"Look at his high unfavorable ratings," host David Gregory said. "At 50%. The highest of any candidate running in recent memory. This is an image problem that his philosophical statements in this speech in May to fundraisers only exacerbates."
Brooks did not mince words, calling Romney "the least popular candidate in history."
"He has to look at what the president's weakness is," Brooks said. "He's never gonna win a popularity contest."
Brooks added that Romney "does not have the passion for the stuff he’s talking about."
"He’s a problem solver," Brooks said. "I think he’s a non-ideological person running in an extremely ideological age, and he’s faking it."
Polls have brought grim results surrounding Romney's favorability, with a late August ABC News/Washington Post survey drawing a 35 percent likability rating.
Romney's 47 percent comments added fuel to that fire. After his comments were leaked on Monday, Brooks conceded that he sees the GOP presidential hopeful as a "kind, decent man" running a "depressingly inept presidential campaign."

"That's not the way I view the world. As someone who grew up in tough circumstances, I know that being on public assistance is not a spot that anyone wants to be in.

"And explain that they don't need to be in that 47 percent. There's no reason for them, for everybody to be -- essentially having given up on their future in this country. There's no reason for it.

"Sure, there are some government programs that cultivate patterns of dependency in some people. I'd put federal disability payments and unemployment insurance in this category.

"It remains important for the country that Romney wins in November (unless he chooses to step down and we get the Ryan-Rubio ticket we deserve!).

"The Romney campaign should double down on what he said. They should own it. The trouble for the left and media (but I repeat myself) is that most Americans agree with Mitt Romney. Most Americans consider themselves part of the 53% and it is not a winning proposition for Barack Obama to convince Americans they are less than they think they are when most Americans already recognize he has made them less than they were," <a href="http://www.redstate.com/2012/09/17/treat-the-press-as-enemy-collaborators/" target="_hplink">Erickson wrote</a> in a blog post on RedState.com.

"I disagree with Governor Romney's insinuation that 47% of Americans believe they are victims who must depend on the government for their care. I know that the vast majority of those who rely on government are not in that situation because they want to be.
