Sean Hannity will attend the 2015 Conservative Political Action Conference (CPAC) this Thursday and Friday, where he will speak to most of the major 2016 Republican presidential candidates, including Ted Cruz, Marco Rubio, Scott Walker, Jeb Bush, Donald Trump and more.

Charles Krauthammer appeared on "Hannity" tonight to break down the field and what he's looking for in a candidate.

Krauthammer said it's not enough just to attack Obama or Hillary, any GOP candidate has to have a program.

"He doesn't have to have a nine-point program, but he has to explain how he's going to address the real problems," Krauthammer said, noting that the worst polling question for Republicans in the 2012 election was, "Which candidate cares about someone like you?"

Krauthammer said Obama won that question 81 percent to 19 percent, quipping that Saddam would have had a higher number.

"You have got to be able to make a connection," he stated. "Some candidates have 'it,' whatever 'it' is. And they're the ones we're going to need."

"I think a young, vigorous, articulate candidate can easily - maybe not easily, but substantively - and without fear go up against Hillary and win."

Krauthammer noted that Republicans destroyed Democrats in the 2010 and and 2014 elections because off-year elections are run on issues.

"In non-presidential years, Republican policies prevail," he said, adding that the question is which GOP candidate can best articulate their case to the American people with energy and intelligence.
