An unusual trend is emerging in the 2008 presidential election campaign: Democrats seem happier talking about God than Republicans.

Whether it is because Mitt Romney is a Mormon, which is off-putting to many evangelicals, or because Rudy Giuliani (a Catholic) is on his third marriage and supports abortion rights, or because John McCain is an Episcopalian (Anglican) and views faith as a private matter, the three Republican frontrunners see little percentage in bringing God into the discussion.
