"Now is not the time for quitting," Kristi Burton Brown said during a morning news conference held on the west steps of the Colorado State Capitol. "Now is the time for stepping forward."
Amendments 48 (in 2008) and 62 (in 2010) both sought to, in essence, ban abortions by defining the beginning of life at the moment of fertilization (or "biological development" as suggested in Amendment 62). Neither received more than 30 percent of the vote.
The 2012 effort relies on a somewhat different language. For the first time, it prohibits all abortions, even in the cases of rape or incest, but in the end it attempts to do essentially the same thing as both 48 and 62.
"We believe in a cause - that all innocent people must be protected," Burton Brown said.
Opponents say it's time to stop.
"I think the voters have spoken out emphatically that they believe this is a personal choice," NARAL (National Abortion Rights Action League) Pro-Choice Executive Director Emilie Ailts said. "I think that [the latest effort] is flying in the face of the wishes of the voters in this state."
"I believe that it's very unfortunate that they spend every day of their lives working very hard to restrict the rights of women and their families," she added.
This month, Mississippi voters failed to support a personhood measure that would have defined the beginning of life at the moment of fertilization. Some polls suggested the measure had a chance of passing, but in the end it lost when more than 55 percent of the voters voted no.
Other states, from California to Florida, are considering similar personhood measures for the 2012 election.
"This is going to be a long fight," personhood supporter Gualberto Garcia Jones suggested. "We're here for the long haul."
When asked if they would try again in 2014, should the measure not pass in 2012, Burton Brown said, "Yes, absolutely."
