And a pretty large percentage of these self professed "christians" attend services on maybe christmas and easter.
A better question would be how many americans are Practicing or active christians.
I tend to think that many if not a majority of the Easter and Christmas attendees are better Christians in practice than the weekly front pewers. Church, like most humanly organized endeavors, can lend itself to self righteousness, hypocrisy and gossip.

this is probably impossible to quantify: for one thing Americans tell pollsters they attend church more than they actually do. I have a feeling ppl who doubt the existance of God but who live in communities that are strongly religious are unlikely to admit their doubts, even to an anonymous pollster.
I for example pray almost every day, but rarely go to church.
