If you’re having world problems, I feel bad for you son,
I got 99 problems, but a Mitt ain’t one.

Big Boi (OutKast) • “War” • 2003

I rap about the Presidential Election and the scandal
that followed;
And we all watched the nation, as it swallowed
And chalked it up…basically, America, you got fucked.
The media shucked and jived, now we stuck.
