The businessman-turned-GOP-presidential-candidate continues to push his “9-9-9” economic plan and point to the economic progress in Chile as an example of how the United States can get back on its feet.

But we need a little more from Cain in Thursday night’s Fox News GOP debate.

Cain has so far been unwilling or unable to engage with the other candidates and compare and contrast his message. Even as the other candidates ganged up on Rick Perry at the last debate, Cain was notably absent from the fray.

If he wants to get noticed, though, Cain is going to have to mix it up.

There is an emerging sense that Cain has reached a plateau in the race in the mid-single digits, and so far there is little reason to doubt that perception.

Strong oratory can get you somewhere, but until you provide something else that the other candidates don’t, you will be relegated to the second tier, which is where Cain has been for the vast majority of the presidential campaign so far.

And unless he can do something to change that dynamic, it’s going to be hard for him to break into the first-tier of the race.
