WASHINGTON — An anti-abortion group plans to launch a bus tour next week through five key states in this year's White House race to highlight President Barack Obama's "extreme" record on the polarizing issue.

The Susan B. Anthony List (SBA List) on August 20 will embark on a tour of 30 cities in five swing states -- Iowa, Wisconsin, Ohio, Virginia and Florida -- with a bus banner reading: "Women Speak Out: Abortion is Not Health Care."

The bus passengers will call for the defeat of Obama and his "team of fellow abortion extremists in Congress" in the November 6 election, the group said in a statement.

The group meanwhile lauded Paul Ryan, tapped Saturday to be the Republican vice presidential candidate, as a "longtime pro-life advocate," further cementing his popularity among the party faithful.

The group accuses Obama of having expanded taxpayer funding of abortions through his landmark health care reform, which allows federal subsidies to be used to cover abortion in cases of rape, incest or to save the mother's life.

The 2010 health care reform law -- which will expand medical coverage to some 32 million Americans -- specifies that federal funds are not to be used to cover abortions for other reasons.

The SBA List will also demand that the US government cut off funding to Planned Parenthood, which provides discounted medical procedures -- including abortions for as little as $300 -- to low-income women.

Republicans have long called for the overturning of Roe v. Wade, the landmark 1973 Supreme Court ruling legalizing abortion, and the issue is among the most polarizing in American politics.

Last week Obama sought to rally women voters by accusing rival Mitt Romney's Republicans of wanting to turn the clock back to the 1950s by limiting women's access to contraception and other services.

Obama said a Romney repeal of the health care law would deny vital medical services to women, including in some cases free birth control, breast cancer screenings and other preventive care insurance firms must now cover.
