The photograph of president obama and new jersey governor chris christy was taken in the aftermath of hurricane sandy? which presidential role does it illustrate?

The photograph of President Obama illustrated that he was doing the role as a chief citizen. As the chief citizen, it is the President's job to represent the people and work for the public interest. Since he is the President, he automatically gets the role as a chief citizen, and will represent the citizens. It's the President's job to get the trust in the citizens, and if he doesn't accomplish that, it'll ruin his reputation.

the main reason that the constitution did not proclaim all men to be free and equal is because of the issue of slavery.
