As reported already in the National Catholic Register, the Blunt amendment has done down to defeat in the US Senate largely on party lines with 51 Senators (mostly Democrats) voting against religious liberty an 48 Senators voting for a return to the status quo.
But to say the vote broke down along party lines does not paint a complete picture. This has been painted by the media as a Catholic issue because the contraception mandate is mainly directed against and primarily impacts Catholic institutions. But the fight for religious liberty is not just a Catholic one. Senator Blunt himself is a Baptist. Those standing up for religious liberty included many Senators who voted for these protections were not Catholic.
