Important Census Document! [not]

I received a curious document in the mail a couple of weeks ago. The envelope was, in fact, labeled as an "Important Census Document." Calling that misleading is putting it kindly. It was, in fact, a mailing from the Republican Party. It was sent to me because I am special. I was chosen as one of a very very few select individuals to answer the enclosed political poll on behalf of all the Republicans in my congressional district. I owed this honor to my "unswerving support for the Republican Party through the years."

All of this seems remarkably unlikely, especially after more than 30 years of faithfully attending DFL precinct caucuses and district conventions. The poll was an odd mixture of fairly neutral sounding questions and ridiculous push questions ("How do you feel about President Obama's agenda to nationalize the health care system?") At the end was an opportunity to include a contribution to the Republican Party along with my answers, but that wasn't pushed especially strongly.

I was briefly tempted to send it back with straight Democratic answers to everything ("Yes! I am wildly in favor of President Obama's out of control spending!") It would be great if they really HAD somehow mistaken me as a good representative of Republican sentiment in my Congressional district (assuming there IS any Republican sentiment in the Fifth District). But it seems far more likely that this was a mass mailing trolling for more Republicans to add to their mailing list.

So I didn't return it. But I'm wondering if anybody else I know got one of these?
