"I believe that in the year 2004 we deserve a president who understands that a stronger America is where women's rights are just that, rights, not political weapons to be used by politicians of this nation," Kerry said during a rally he had scheduled with women's rights groups.
"More than 30 years after Roe vs. Wade became the law of the land, it has never been more at risk than it is today," Kerry said. "We are going to have a change in leadership in this country to protect the right of choice."
Earlier Friday, Cardinal Francis Arinze would not comment on whether it was right to give Communion to Kerry, who is Catholic. Arinze spoke to reporters while issuing a Vatican directive, commissioned by Pope John Paul II, that clamps down on liturgical abuses in Mass. The 71-page document does not address the question of pro-choice politicians, an issue reporters raised with the cardinal.
When asked in general about "unambiguously pro-abortion" Catholic politicians, Arinze said such a politician "is not fit" to receive Communion. "If they should not receive, then they should not be given," he said.
Kerry spokesman David Wade would not respond directly to Arinze, but he reiterated Kerry's position on the separation of church and state that "helped make religious affiliation a non-issue in American politics."
"The decisions he will make as president will be guided by his obligation to all the people of our country and to the Constitution of the United States," Wade said in a statement. "Every American — whether they be Jewish, Catholic, Protestant or any other faith — must believe their president is representing them."
Bush campaign spokesman Steve Schmidt said: "John Kerry's position in favor of partial-birth abortion shows how far outside the mainstream he is. The president supports a culture of life."
Kerry scheduled the rally to compare his stand on abortion with what he says are Mr. Bush's extreme anti-abortion positions. On Sunday in Washington, the National Organization for Women, NARAL Pro-choice America, the Planned Parenthood Federation and other groups plan to march for abortion rights.
The Planned Parenthood Action Fund endorsed Kerry on Friday, citing his support for abortion rights. Planned Parenthood's political arm, which has never before endorsed a presidential candidate, said it will focus on bringing single women to the polls in November.
Judy Brown, president of the anti-abortion American Life League, said the cardinal's comments "should reinforce for the bishops that they must enforce canon law" by denying Communion to public figures who advocate abortion. She estimated that more than 500 politicians at the state and national level fall into that category.
"My impression is that the vast majority of bishops do not enforce the law," Brown said.
Kerry's position of being personally opposed to abortion but supporting abortion rights is hypocritical, Brown said. "There is no such thing in the Catholic Church as personal morality. There's only right and wrong," she said.
Frances Kissling, president of Catholics for a Free Choice, USA, said statements such as Arinze's "debase the political campaign" and would isolate the church from its Americans members, most of whom she said support abortion rights.
"Do they really want to tell Senators Kennedy, Mikulski, Leahy and 70 other members of the U.S. Congress that they can't receive Communion?" Kissling asked. "Because they can't just tell this to Senator Kerry."
Last week, , the Washington archbishop heading a task force examining whether there should be church sanctions for Catholic politicians who support abortion rights.
Kerry has told supporters during campaign events that openings on the Supreme Court in coming years could jeopardize the right to abortion.
"If you need any motivation, let me give you three little words: the Supreme Court," he has said.
President Bush approves of abortion only in cases of rape or incest or when the pregnancy endangers a woman's life.
Mr. Bush recently signed two pieces of legislation that have alarmed abortion rights advocates. The first bans the procedure that critics describe as ; the second established by making it a separate crime to harm a fetus during an assault on the mother-to-be.
The president was in Florida on Friday, campaigning for a second straight day on his commitment to protecting the environment, an issue that has brought steady criticism from Democrats and environmental groups for the past 3½ years.
"I know there's a lot of politics when it comes to the environment, but what I like to do is focus on ... results," Mr. Bush told an audience of several hundred supporters at the environmentally sensitive Rookery Bay Estuarine Research Reserve on the Gulf Coast adjacent to the Everglades.
The president made the comments after he and his brother Jeb, Florida's governor, chopped down invasive species of plants that are harming the state's lush wetlands. The president jokingly menaced reporters with a large pair of pruning shears before using them on the undergrowth.
Mr. Bush defended his record in the 21st trip of his presidency to Florida, where he also is headlining two fund-raising events in Naples and Coral Gables.
