I have only 30 minutes in which to speak to you this evening, and I, therefore, will not be able to discuss in detail so much as I can write when I have all of the time and space that is allowed me for the subjects, but I will undertake to sketch them very briefly without manuscript or preparation, so that you can understand them so well as I can tell them to you tonight.

I contend, my friends, that we have no difficult problem to solve in America, and that is the view of nearly everyone with whom I have discussed the matter here in Washington and elsewhere throughout the United States—that we have no very difficult problem to solve. (1-2)

The opening lines are absolutely perfect for the format of the speech that follows. Long declares he only has so much time, and as much as he'd like to get into the nitty-gritty of the problem facing America and Long's proposed solution, there's only enough time for a quick overview rather than lots of explicit detail. By telling his listeners that the problem he's about to address is easy-peasy to solve, it sets up his proposed plan as the simple and obvious solution.
