Quote #4
I hope you can see, my friends, from this essential recital of what your Government is doing that there is nothing complex, nothing radical in the process. (57)
Transparency is the name of the game here. Roosevelt is saying that he's not up to anything shady, and he's not trying to trick the American people. He's not trying to change the entire system (that'd be the "radical" part). He is saying that people need to be patriotic by believing that their government has their best interests in mind.
Quote #5
I can never be sufficiently grateful to the people for the loyal support that they have given me in their acceptance of the judgment that has dictated our course, even though all our processes may not have seemed clear to them. (67)
A great way to encourage loyalty and patriotism is to thank people for it. What's funny here is that whether or not Roosevelt actually has the support of his people, by thanking them for it everyone will assume that the nation does support him, so they'll go along with it.
