I think I am going to print up a bumper sticker that reads, "Don't blame me, I support a benevolent Hapsburg monarchy."
Other ideas:
"Don't blame me, I voted for Jefferson Davis."
"Don't blame me, I supported the Anti-Federalists."
"Don't blame me, I supported the Cavaliers."
"Don't blame me, I supported the Vendée."
"Don't blame me, I can comprehend Amendment X."
