I was looking at Obama's 2004 democratic convention speech.
He said "crossroads of a nation, land of Lincoln, let me express my deepest gratitude..."
I think "land of Lincoln" is referring to Illinois, Lincoln's home state.
So, what is "crossroads of a nation", is that Chicago heights? But that's "crossroads of THE nation" according Wiki.
Where did he learn his writing style? Is it from Martin Luther King, Jr and JF Kennedy?
