I doubt it. Conservatives are more responsible and likely to fill out the basic information than many liberal scum. They may not fill out all fields but they will fill out the basic info.
I mailed it two or maybe three days after receiving the form. A week later I received a post card asking me to return quickly if I had not already done so.
First a letter telling me I would be receiving the census form. Next got the form, then the follow up post card. Wasteful people in charge. Never remember this happening before.
