Washington, DC (LifeNews.com) -- One of the top pro-abortion groups in the country told its membership last week that several of the main Republican presidential contenders couldn't get its support because they're pro-life on abortion. Of the leading names, only pro-abortion ex-New York City mayor Rudy Giuliani was not included for criticism.

The pro-abortion group NARAL told its members that it also expects one more candidate to enter the race who is "bent on taking away a woman's right to choose: Fred Thompson."

"Thompson joins a cadre of candidates who are clamoring to out anti-choice each other," the organization's president Nancy Keenan said. She told her membership to "not be fooled" despite a much-maligned recent Los Angeles Times article that appeared to erroneously claim Thompson once lobbied for a pro-abortion group.

NARAL made it clear it believes Thompson is fully pro-life on abortion issues.

"Fred Thompson is no better" than the other Republican candidates, according to Keenan. "During his seven years in the U.S. Senate, he voted anti-choice 44 times out of 46 choice-related issues. He has called Roe v. Wade 'bad law' and received a 100 percent voting record from the National Right to Life Committee."

Mitt Romney was the next GOP contender NARAL singled out and Keenan noted he has said, "I am pro-life and I support pro-life legislation.... I think the Roe v. Wade one-size-fits-all approach is wrong."

NARAL next criticized Arizona Sen. John McCain saying he has voted pro-life 123 times out of 128 votes the organization has scored on abortion issues. It also indicated McCain has said, "I do not support Roe v. Wade. I think it should be overturned."

Kansas Sen. Sam Brownback, who has been relying on his pro-life views to gain support more than any of the GOP presidential candidates, also found himself under attack. Keenan complained that he has gone so far as to promise that he "will commit to helping end abortion in America."

Keenan urged her fellow abortion advocates to "stay up-to-date about where the presidential candidates stand on women's freedom and privacy" because "anything can happen between now and the nomination."
