IF you go to Church in the U.S. often Ideology trumps self interest regarding voting

So why does the white, lower middle class, population continue to favor the Republicans despite the fact that the economic promises of the party have been shown to be bogus? Partly it is a cultural phenomenon. The Republican platform is against abortion and gay marriage and for gun rights, important issues for lower middle class whites. Various studies also show that Americans who attend church frequently are significantly more likely to be Republican and less likely to be Democratic. Only 25% of white Protestants who attend church once a week vote Democratic. And 61% of the religiously unaffiliated vote Democratic. These statistics suggest that ideology trumps self-interest.

Why Does the (White) Lower Middle Class Vote Republican?

So, it is easier if you go to church to be in denial of your actual needs for survival of both you and your children? The answer appears to be: 

Yes. 

However, this isn't saying people shouldn't go to church. It just means that in reality they are acting against their personal survival and the survival of their children often when they vote.
