In the second of four installments on how the presidential candidates would lead, Margaret Warner talks to people who have worked closely with Obama over the years about his leadership style and decision making process.

The first seven minutes of the video show several advisers and former colleagues describe Obama as someone who trusts his advisers, encourages unemotional and open debate on issues and makes quick deliberate decisions after that process. He is also described as someone willing to make small concessions if it will serve a bigger purpose.

Continue watching to see former colleague Republican State Senator Steve Rauschenberger add that Obama was a cautious politician who made little effort to compromise with the Republican Party.

"He's very methodical in how he evaluates decisions. He asks a series of questions. He'll engage you in dialogue on the options. And then he'll make a decision. And he doesn't look back at that decision."- David Axelrod, Obama Campaign Chief Strategist

"He listens to various viewpoints. He elicits dissenting views. He weighs those rationally and pragmatically. But then he tends to make a relatively swift and clear decision."- Susan Rice, Obama Campaign Adviser

"We were looking for a Democrat that we could work with and that maybe this was the crossover person that we could get and really make some progress on welfare reform." -Steve Rauschenberger, R-Former Illinois State Senator
