NEW YORK (CBSNewYork) — Catholic leaders upped the ante Monday, threatening to challenge the Obama administration over a provision of the new health care law that would require all employers, including religious institutions, to pay for birth control.

As CBS 2’s Marcia Kramer reports, it could affect the presidential elections.

Catholic leaders are furious and determined to harness the voting power of the nation’s 70 million Catholic voters to stop a provision of President Barack Obama’s new heath car reform bill that will force Catholic schools, hospitals and charities to buy birth control pills, abortion-producing drugs and sterilization coverage for their employees.
