MIAMI — In a year in which most states have steered clear of contentious ballot initiatives, Florida voters are facing two proposed constitutional amendments — one on abortion, the other on the separation of church and state — that could have far-reaching repercussions.

Drafted by the Florida Legislature, along with nine other proposed amendments that will appear on the ballot in November, the first measure would restrict abortions and the second would allow public money to flow to religious institutions — an effort, opponents say, to revive school vouchers. The initiatives would require the approval of 60 percent of voters to take effect.
