Supporters of a campaign to loosen restrictions on embryonic stem cell research in Michigan want to raise between $10 million and $20 million for their proposal targeting the November election.
The Stem Cell Research Ballot Question Committee will have to collect more than 300,000 valid signatures of Michigan voters to make the ballot.
The ballot drive has opposition. Groups such as Right to Life of Michigan and the Michigan Catholic Conference oppose embryonic stem cell research but support adult stem cell research.
Michigan has some of the nation's strictest rules on embryonic stem cell research.
