WASHINGTON - REPUBLICAN presidential candidate John McCain, whose presumptive running mate disclosed that her unmarried 17-year-old daughter is pregnant, has opposed proposals to spend federal money on teen-pregnancy prevention programmes and voted to require poor teenage mothers to stay in school or lose their welfare benefits.

Alaska Govenor Sarah Palin's announcement on Monday about her daughter, Bristol, was aimed at rebutting Internet rumors that Palin's youngest son, born in April, was her daughter's. Mrs Palin said her daughter intends to raise her child and marry the baby's father, who was identified only by his first name, Levi. The baby is due in late December.

Mr McCain's record on issues surrounding teen pregnancy and contraceptives during his more than two decades in the Senate indicate that he and Mrs Palin have similar views. Until Monday, when the subject surfaced in a deeply personal manner, teen pregnancy and sex education were not issues in the national political campaign.

Mrs Palin herself said she opposes funding sexual-education programmes in Alaska. She has supported abstinence programmes in schools.

'The explicit sex-ed programmes will not find my support,' she wrote in a 2006 questionnaire distributed among gubernatorial candidates.

Mr McCain's position on contraceptives and teen pregnancy issues has been difficult to judge on the campaign trail, as he appears uncomfortable discussing such topics.

Reporters asked the presumptive Republican presidential nominee in November 2007 whether he supported grants for sex education in the United States, whether such programmes should include directions for using contraceptives or whether he supports President George W. Bush's policy of promoting abstinence.

'Ahhh, I think I support the president's policy,' Mr McCain said.

When reporters pressed Mr McCain whether the government should provide contraceptives or counseling on contraceptives, he replied: 'You've stumped me.'

Mr McCain said later that he was sure he opposed government spending on contraceptives.

The McCain campaign did not respond on Monday to repeated requests for information.

In Senate votes, Mr McCain has opposed some proposals to pay for teen-pregnancy prevention programmes. In 2006, Mr McCain joined fellow Republicans in voting against a Senate Democratic proposal to send US$100 million (S$143 million) to communities for teen-pregnancy prevention programmes that would have included sex education about contraceptives.

In 2005, Mr McCain opposed a Senate Democratic proposal that would have spent tens of millions of dollars to pay for pregnancy prevention programmes including education on emergency contraception such as the morning-after pill; teen-pregnancy prevention programmes except abstinence-only education; and required insurance companies that cover Viagra also to pay for prescription contraception.

Mr McCain voted for the Family Support Act in 1988, which passed overwhelmingly in the Senate and required teen mothers who receive public assistance to remain in high school and, in some cases, to live with their parents.

'Young parents who have not completed high school will be required to stay in or return to school to complete the basic education so necessary to a productive life,' said President Ronald Reagan, as he signed the law in October 1988.

Mr McCain cited abortion, sex education and birth control as some of the issues on which he differed with Joycelyn Elders, former President Bill Clinton's nominee for surgeon general. He quoted Elders as telling lawmakers that abortion has had positive health effects, including reducing the number of children 'afflicted with severe defects'.

'As a father of a number of young children, including an adopted daughter who was born with a birth defect, I am deeply, deeply troubled by these views,' Mr McCain said in a 1993 speech opposing Elders' confirmation.

Mrs Palin's fifth child, a son named Trig, was born in April with Down syndrome, a genetic abnormality that impedes physical, intellectual and language development. Conservatives supportive of Mrs Palin as Mr McCain's running mate have praised her choice to deliver Trig even after the family learned about his condition during prenatal testing.

Mr McCain said the country unarguably had a problem with teen pregnancy, but he said Elders' approach would make it worse. He said Elders started a program to distribute condoms in schools, but the rate of teen pregnancy rose in those counties. When it turned out many of the condoms were defective, Elders decided to continue the programme rather than halt it or inform the public of the risk, Mr McCain said. -- AP
