Given the events of the past 24 hours at the Democratic National Convention, this suddenly becomes a fair question. Yesterday, delegates went ballistic when party officials tried to reinsert previously omitted language about God and Israel into their platform. Needless to say this created some bad optics for the Democrats as well as creating news at their convention. This was such a grave unforced error it's not clear yet how much damage has been done.
But taking this in conjunction with the party's full fledged endorsement of abortion on demand (“The Democratic Party strongly and unequivocally supports Roe v. Wade and a woman’s right to make decisions regarding her pregnancy, including a safe and legal abortion, regardless of ability to pay. We oppose any and all efforts to weaken or undermine that right.”) as well as the ongoing controversy over the HHS mandate regarding conception and suddenly you get the feeling that there is outright animus towards people of faith.
This is not necessarily new but never has it been more obvious. As John Hinderaker points outs, "The Democrats, bluntly put, have become the party of those who don't go to church." Although I would disagree with him over whether religious beliefs informs ones view of the issues of the day (it does) he is absolutely correct to suggest that the Democratic platform is in direct opposition to the values that Jews, Christians, and Catholics in particular hold.
This point is further illustrated in Al Mohler's excellent essay on the stark worldview choices we are facing in this election.
All of this begs the question whether a devout Jew, Christian or Catholic can sincerely also identify themselves as a Democrat. I frankly can't see how anyone can.
