This study was published last year, it's about changes of opinion on a value question among major religious groups during 5 years time period:
In 5 years period of time, Christian groups have changed their answer 42%(!), 22% and 16%. The religiously unaffiliated 3%. The 3% change of non-religious could be actually explainable by factors like generational replacement without anyone actually changing their mind in 5 years.
Because all the groups were exposed to the same campaigning and news coverage, it seems to me like Christian value commitments are by far much more superficial and more likely to flip around with political trends, while the values of religious nones (atheists, apatheists, spiritual-not-religious etc) are deeply held and remain unchanged under such political pressure.
Also, Christians typically claim to have absolute values. To both claim to have absolute values and yet have more shaky values than the people who don't even claim that, is a double-failure.
I think that the conclusion here appears to be that the Christian value system does not in practice create the kind of people who actually have deeply held, let alone absolute, values. Quite contrary, it appears to work the opposite way and create people who's values are easily shaken by political trends, far more so than the values held by non-religious people.
Please note: The question is neither about whom people intend to vote, nor it's a hot political issue - question. It's a timeless value question, whatever someone answers to that, would be true for an ancient Roman Emperor as well as for 21th century president.
