Babelfish says:
Isn't that a democrat? Is the one democrat! Isn't those a dirty rat? Is the one dirty rat!
What I translated was;
Is that not a Democrat? Yes that is a Democrat! Is that not a dirty rat? Yes that is a dirty rat!
It's a parody of the German drinking song, "Schnitzlebanc".
Better German would have been:
Ist das nicht ein Demokrat? Ja das ist der ein Demokrat! Ist das nicht eine schmutzige Ratte? Ja das ist eine schmutzige Ratte!
Der and Die have gender, but Das does not.
Translation:
Is that not a Democrat. Yes that is a democrat. Is that not a dirty rat. Yes that is a dirty rat.
