AP 09/11 20:05 EDT V0043 WASHINGTON (AP) -- Pat Buchanan brought 2,000 Christian conservatives to their feet Saturday with a fiery defense of the Republican Party's antiabortion stance and a vow to rebuff GOP moderates and never "raise a white flag in the cultural war." It was Buchanan and his audience of Christian Coalition activists that moderates blamed for George Bush's defeat last year, but the parade of 1996 GOP presidential prospects at the weekend meeting was a testament to the Christian right's strength in Republican politics. The weekend session also was the first test of the Christian Coalition's pledge to diversify from its traditional social agenda, and the sessions demonstrated the challenges of fulfilling that goal without alienating the religious conservative movement's core supporters. From Buchanan's reception, for example, it was clear the Christian activists are energized most by conservative cultural issues. "If a political party would turn its back on the 4,000 unborn children doomed to death every day in this country then it is time to found a new party," Buchanan said, prompting a standing ovation. "We are a pro-life party and we are going to keep our party pro-life." The conservative commentator, who mounted an unsuccessful primary challenge to Bush last year, won rousing applause again with an attack on "multiculturalism," scoffing at those who say the world's many cultures are equal. "Our culture is superior," Buchanan said. "Our culture is superior because our religion is Christianity and that is the truth that makes men free." It is such talk that moderates claim gave Republicans an intolerant image last year and drove many suburban middle-class voters away. "It cost us the election," said Elsie Hillman, a moderate Republican National Committee member from Pennsylvania. Hillman's was a common view among Republicans after the election, and even many conservatives said their movement needed a softer image. But eight months into the Clinton administration, many Christian conservatives are more optimistic, believing they have gained strength thanks to Clinton. Still, not all of the GOP presidential prospects were as eager as Buchanan to plunge into the party's internal debate over abortion and other social issues. In speeches Friday, Sens. Bob Dole of Kansas and Phil Gramm of Texas focused on economics and health care. "We don't need any litmus tests in the Republican Party," was as close as Dole came to talking about the abortion debate. "We need to learn to focus on the big picture," was Gramm's indirect reference. Former Housing Secretary Jack Kemp, speaking Saturday night, said it is a "false choice" to pit social conservatives against economic conservatives. But there is no debate on that point among the conservative Christian. And Kemp, in a rambling speech in which he at one point discussed the Greek and Latin sources of the word "economics," skirted any direct reference to moderates or the abortion feud. Buchanan showed no such reluctance and was by far the best received of the four. "We cannot raise a white flag in the cultural war because that war is who we are," he said.
