"The most important thing is now to talk about the latest poll numbers and how the people of California feel and how the people in America basically feel," he said on NBC's "Meet the Press."

He said polls show that nearly 70 percent of voters want politicians to work together. 

"I think it is important that we go and bring both of the parties together. The more we go to the left, the more we go to the right, I believe of what President Eisenhower said, 'Politics is like the road. The left and the right represents the gutter, and the middle is drivable.' "

He said he is trying to stay focused on the issues.

"It's important that the people know how they feel and in which direction to go, and it also will help the candidates to listen to the people carefully, and not to deviate from that and to really talk about those very important issues, since we have the primaries coming up in California," he said.

"I think the presidential candidates, whoever they are, have to address those issues."

When he does make an announcement, though, Schwarzenegger said he will do it in an "unusual" way.  

"So I will study the various different candidates, what they represent, all of them, and I will then make up my mind and I would make the endorsement. So I will make an endorsement, but it will not be here, because then that would be the headline."
