What's in a Name?

OK, this one is a bit controversial... but it was fun making it...

It's not just a political poem, there is something unique about it... what is it?

SH!! America, rob us a bank
As I ambush a broken car
He mocks USA... Barbarian,
A bonk is Abraham's cure.
Obama B.S. crier = Kahunas
I earmark a boss a bunch.
Iran, a BM, habeas corkus
Ha! ACORN, kiss a bare bum!
