That's fair - Obama hasn't attracted attention to his Christian beliefs except when combating accusations that he's a secret Muslim or when a photo-op is required outside a church on Easter or Christmas, etc.
And see, from the start, I never took Palin's comment as being related to religion. Granted her words were spoken, but in any recap I've seen the word baptism/baptized is not capitalized, as it would be if a Christian was using it in the sacramental sense, nor did she speak about Baptizing terrorists "into the church" which is what the sacrament entails. She more spoke about baptism in a more secular way, as in "introducing" terrorists into the way she, as leader of the country, would operate. As well, this was basically a keynote speaker kind of rouse the crowd oratory that she's come to be famous for and not anything in the way of a serious policy discussion that would go along with a run for office.
Anyway, we all look at these things differently and perhaps I give her a little more slack than some because I find her refreshingly blunt and entertaining in the way she approaches public and political issues/discussions. She's doesn't have the canned, politically correct answers to all controversial questions. She's pretty much reached the stage, for me, of the old grandmother who'll blurt out something outrageous and everyone has a good laugh. I remember considering Ann Richards, the former Democrat Governor of Texas in the same way after she left politics - refreshingly candid.
