The latest polls show tight races in three states with marriage amendments.
In California, a poll released Friday shows opponents of Proposition 8, which would define marriage as between one man and one woman, slightly ahead with a 49 percent to 45 percent edge.
The poll was based on a random sample of 966 likely voters conducted from October 18-28, and has a sampling error of plus or minus 3.3 percentage points.

And in Florida, Amendment 2 would put language in the state constitution saying that marriage is only for one man and one woman. A Mason-Dixon poll last week shows it has 56 percent approval, with undecided voters at 7 percent.
The amendment needs 60 percent of voters to pass it.
"We have a full-blown campaign," John Stemberger, of Yes2Marriage.org, said. "We have TV ads, radio ads, full-blown mail but the problem is we are outspent 3 to 1 and so we are counting on church groups, grass-roots, ordinary people who understand why this is important - to vote yes on amendment 2."
In Arizona, Prop 102 would also define marriage the same way in the state constitution.
Arizona voters defeated a similar measure two years ago.
Recent polling shows 49 percent support it, 42 percent oppose it and 9 percent are undecided.
But it's California's marriage amendment, Proposition 8, which has garnered the most attention and money nationwide - with $60 million pouring into it from both sides.
Thousands are expected tomorrow at San Diego's QUALCOMM Stadium for a rally supporting Prop 8. Dr. James Dobson of Focus on the Family and other Christian leaders will speak.
Meanwhile, gay activists like Tim Gill are working covertly to see that legislation supporting gay marriage gets passed.
CBN News first reported this spring that Gill was targeting New York.
His plan: Turn the state senate over to Democratic control, which would allow it to pass a gay marriage bill.
The New York State Assembly has already passed one. But as of March, few lawmakers knew about what was going on.
CBN News: Have you heard of a gay rights activist from Colorado named Tim Gill?
Lawmaker: No, I have not.
CBN News: Are you aware of his influence in New York?
Lawmaker: I haven't seen it in New York.
Campaign contributions show homosexual activists around the country have poured over a million dollars into tipping New York's statehouse.
