Right to Life of Michigan makes available such a comparison of the two major candidates on abortion and other life issues for free at its website, in both English and Spanish (scroll down to "Stark Contrast"). The organization urges that people copy and freely distribute this comparison sheet.
The actual flyer is in PDF format at this link. It is a one-page flyer, with nine bullet points comparing George W. Bush and John Kerry on the Life issues. It is concise and purely comparative. It reports the facts and lets the voter decide whom to vote for. The flyer itself does not endorse one candidate over another, although it does mention the fact that Bush is endorsed by numerous prolife organzations including Right to Life of Michigan. This factual disclosure is necessary so that no one can allege that the source of the flyer is trying to somehow misrepresent itself as neutral on the Life issues.
