I am suspicious of polls, unless the methodology is meticulous. But if it is true, that even most mainline Protestants believe their good works can save them, then they have entirely missed the whole point of the Gospel. Some of the causes are related to lack of personal interest in reading and reflecting on the word of God, while, in my view, poor preaching of the word. Although some pastors preach the word faithfully and actually teach their congregations, too many others give standing monologues filled with jokes, cultural observations, personal anecdotes, and avoid substance in their messages, rendering themselves into the role of entertainers. The church needs strong preaching, lest erroneous doctrines and downright heresy lull the congregation to sleep. Individual Christians must also take the responsibility of reading the word regularly and prayer. Otherwise, being a Christian is like belonging to just another social club.
