"He's playing the actual president already IMO concerning international situation's."
Thats because he is SecState, and it is his job to concern himself with international situations.

He is part of a team that was carefully put together, and that is working brilliantly and correctly.
The reasons he is well liked have been bought up to some extent: That he is a moderate, an American success story, and an embodiment of the American Dream in that respect, having rose from the Bronx through hard work and application. He is also liked and respected because he is very much associated with the victory in the Gulf War, where he made regular public appearences as the "face of the military" in that campaign, and also helped craft strategy.
He is experienced in military matters, something that is important for an effective foreign minister. But most of all, he is an effective diplomat, but not a career diplomat, who often carry the State Department's own agenda. He is not a politician, but knows politics
I agree also with Knowltok's analysis that "...he is what white people want black people to be like...He is well spoken and educated, is more concerned with the business of running whatever he is in charge of than some social agenda, and is a great role model for anyone."
Out of him, and Rudolph Giuliani, two most admirable and upright men, I dare say that Powell would make a better President due to his experience on the international scene, but Giuliani has a very good record in his managment of NYC. Powell will also be on the scene for longer.
SecState as potential President? Something you couldn't really say for Alexander Haig ("I am in charge here!"), Dr Henry, or even ol' Madeline Albright
