Name a single president who has lived up to your definition of Christianity. I get so tired of this...Ford was divorced and drank. Reagan was divorced. The Bushes are certainly not part of any conservative church.
Our elected officials are human. We are not voting in our church officials. There are those who will never vote for a Roman Catholic for they think that religion is completely of Satan.
the arguments get ridiculous. I would rather have a Penn Gillett in my corner than a Barack Obama or Bill Ayers
Well, indeed there were some horrific examples of so-called "Christians" in office...I can think of, for example...
...Warren Harding (Baptist)
...Stephen Grover Cleveland (Presbyterian)
But, to answer your challenge: Teddy Roosevelt in the early 1900s wasn't perfect by any means; but he embraced many standards...and fleshed many of them out well...Teddy R. was the first POTUS to invite a non-caucasian (Booker T. Washington) in to dine in the White House a half-century away from reformers like Martin Luther King...
