Here is an interesting interview by NRO with Brian Golden a Democratic state representative from Massachusetts.
Rep. Golden: If you look at it objectively you can see a profound difference. When John Kennedy spoke to people about his religion, he was essentially saying, "I’m a Catholic, but don’t hold it against me." John Kerry essentially says, "I’m a Catholic, but don’t hold me to it."
It’s one thing if you don’t believe that human life begins at conception. However, John Kerry admits he believes that life begins at conception but won’t do anything to protect it in law. How does he square his conscience with his official antipathy to all legislation protecting human life? John Kennedy said that "if the time should ever come…when my office would require me to either violate my conscience or violate the national interest, then I would resign the office; and I hope any conscientious public servant would do likewise." Can you imagine that coming from John Kerry? Senator Kerry’s willingness to place political expedience before conscience is disturbing no matter what your faith.
