WASHINGTON – The House of Representatives on Wednesday approved a sweeping anti-abortion package to further distance federal funds from the procedure by solidifying existing measures and imposing new ones.

The measures stand little chance of approval by the Senate, but again demonstrated the key role social issues still play in unifying the Republican Party.

Dubbed the “No Taxpayer Funding for Abortion Act,” the bill was approved along party lines and endorsed by long-time abortion foes and the House Republican leadership, despite arguments that GOP lawmakers should keep a narrow focus on budget and spending issues.

The bill passed 251-175.

Both of Maine’s representatives, Democrats Chellie Pingree and Michael Michaud, voted against the package.

Republicans demanded the anti-abortion measures as part of contentious budget discussions earlier this year – nearly tanking bipartisan talks and risking a government shutdown. The provisions were removed in a deal with the White House to enable passage of the budget measure on the condition that a separate vote be held later to allow members to express their views on the record.

The House bill would permanently place into a law current policies prohibiting federal money from paying for abortions through Medicaid and some other federal programs. The policies, primarily outlined in the decades-old measure known as the Hyde Amendment, must be periodically renewed.

But the bill also goes further to eliminate what supporters say are indirect federal subsidies for abortion providers.

Under the measure, businesses that offer health insurance policies covering abortion could not recoup tax credits under the new health care law. In addition, individuals could not deduct the cost of an abortion when itemizing health expenses on their taxes, nor could they use tax-exempt savings account to pay for an abortion.

The bill includes exceptions for pregnancies that threaten the life of the mother, or result from rape or incest.

Similar measures were introduced and defeated during the debate over the health care law in 2009.

As Democrats sought to portray these new provisions as part of an extreme social agenda, many Republicans argued the measure merely reflect the public’s will. Rep. Chris Smith, R-N.J., the bill’s sponsor and chief advocate, said he hoped the bill would limit access to abortion.

“There is no doubt whatsoever that ending all public funding for abortion saves lives,” said Smith, a leading congressional abortion foe. “When public funding and facilitation isn’t available for abortion, children have a greater chance for survival.”

Democrats and abortion rights advocates argue the legislation amounted to a tax increase on small businesses.

They claimed the tax deduction provision could force victims of rape or incest to have to show proof of the crime to an IRS agent.

“We should not use the tax code to force women to relive their ordeal to a IRS agent,” said Rep. Jackie Speier, a California Democrat who recently revealed in an emotional floor speech that she once had an abortion.
