Most Michigan voters are against an effort to require that women purchase insurance riders for non-emergency abortion coverage, according to a recent poll.

The survey by Marketing Resource Group and Mitchell Research and Communications found that just 36 percent of registered voters support a Right to Life of Michigan effort to exclude abortion coverage from both private and public health insurance and requiring that women buy a separate insurance rider for such coverage.

That compares to 53 percent that oppose the requirement.

Right to Life filed over 300,000 signatures with the Secretary of State earlier this month to exclude elective abortion coverage from basic health plans.

If the signatures are verified the proposal would go to the Legislature, where lawmakers could then give it final approval. If they don't, the proposal would go up for a statewide vote.

The phone survey of 600 potential voters was taken October 6-10. It has a margin of error of plus or minus four percentage points.
