Watch the Obama Speech from about 8min in and read the transcript. What techniques does Obama use that MLK use?

But the reason our campaign has always been different, the reason we began this improbable journey almost a year ago is because it's not just about what I will do as president. It is also about what you, the people who love this country, the citizens of the United States of America, can do to change it.

That's what this election is all about.

That's why tonight belongs to you. It belongs to the organizers, and the volunteers, and the staff who believed in this journey and rallied so many others to join the cause.

We know the battle ahead will be long. But always remember that, no matter what obstacles stand in our way, nothing can stand in the way of the power of millions of voices calling for change.

We have been told we cannot do this by a chorus of cynics. And they will only grow louder and more dissonant in the weeks and months to come.

We've been asked to pause for a reality check. We've been warned against offering the people of this nation false hope. But in the unlikely story that is America, there has never been anything false about hope.

(APPLAUSE)

For when we have faced down impossible odds, when we've been told we're not ready or that we shouldn't try or that we can't, generations of Americans have responded with a simple creed that sums up the spirit of a people: Yes, we can. Yes, we can. Yes, we can.

It was a creed written into the founding documents that declared the destiny of a nation: Yes, we can.

It was whispered by slaves and abolitionists as they blazed a trail towards freedom through the darkest of nights: Yes, we can.

It was sung by immigrants as they struck out from distant shores and pioneers who pushed westward against an unforgiving wilderness: Yes, we can.

It was the call of workers who organized, women who reached for the ballot, a president who chose the moon as our new frontier, and a king who took us to the mountaintop and pointed the way to the promised land: Yes, we can, to justice and equality.

Yes, we can, to opportunity and prosperity. Yes, we can heal this nation. Yes, we can repair this world. Yes, we can.

And so, tomorrow, as we take the campaign south and west, as we learn that the struggles of the textile workers in Spartanburg are not so different than the plight of the dishwasher in Las Vegas, that the hopes of the little girl who goes to the crumbling school in Dillon are the same as the dreams of the boy who learns on the streets of L.A., we will remember that there is something happening in America, that we are not as divided as our politics suggest, that we are one people, we are one nation.

And, together, we will begin the next great chapter in the American story, with three words that will ring from coast to coast, from sea to shining sea: Yes, we can.

Thank you, New Hampshire. Thank you. Thank you.

Answer: Makes it not about himself and talking about their responsibility and what him and they will do. He uses a bit of repetition with the "Yes we can". He is using a catch phrase, MLK uses I have a Dream and Obama uses "Yes we can". He was referencing back to the founding documents, which uses facts that all the people believe in. Using Ethos with the founding documents makes his speech stronger because everyone finds this important. He calls to the different parts of the land just like MLK did with Mississipi and other states. Obama says, "

the struggles of the textile workers in Spartanburg are not so different than the plight of the dishwasher in Las Vegas". This is just like what MLK was doing in his speech (reaching out to the different states). He brought children into it just like MLK did with his children. When he is talking about them all being one nation this is very similar to one of MLK's speech. In the Gettysburg Address, Abraham Lincoln also uses this in his speech. He ends it with "Yes we can". He left it with the word that he was repeating throughout the speech, just like MLK.
