You asked, “why did 20% of white evangelicals vote for Obama? why would evangelicals vote Democrat?”
That is like asking “why did the Corinthians think of men above that which is written?” (1Cor. 4:6)
You mean, “Why did 20% of Born again Evans vote like twice as many white Catholics?,” and why did only a 10% majority of even white Catholics vote like 70% of Evans?
I am not sure what your reasoning is supposed to prove, but it appears you are attempting damage control
by resorting to invoking the minority of Born again Evans who voted liberal like in in order to minimize that only 48% of Catholics voted for Romney, and just 59% white Catholics did, versus 69% of BA Evans and 57% of Prots overall. - , http://www.pewforum.org/Politics-and-Elections/How-the-Faithful-Voted-2012-Preliminary-Exit-Poll-Analysis.aspx
There simply is no debate that evangelicals are more conservative (though as foretold [2Thes. 2:3], this is in decline), and that only a minority of Evans voted like Catholics usually do, and are contrary to their profession, or that while conservative RCs voted for Romney, yet overall those whom Rome counts and treats as members in life and in death are liberal: http://www.peacebyjesus.com/RC-Stats_vs._Evang.html
your posts are accusative yet not giving a response for why evangelicals, white evangelicals with no historical baggage of Democrats vote for them -- do you have any reason for why evangelicals voted for OBama?
Nah, hardly damage control.
The majority of Catholics voted for Trump - what about your particular flavor of Christianity? Or is it a church of 1, so 100% voting for T?
The Pew analysis shows that white evangelicals overwhelmingly supported Romney (79%), which is indeed higher than white Catholics (59%) or white mainline Protestants (54%). However, this doesn't prove evangelicals are inherently "more conservative" in a way that diminishes Catholics; it reflects demographic and cultural differences. For instance, evangelicals often prioritize issues like abortion and same-sex marriage more uniformly, while Catholics, guided by Church teaching, weigh a fuller spectrum of social doctrine, including care for the poor, immigrants, and the environment (as outlined in documents like Rerum Novarum and Laudato Si'). In 2012, Obama's policies on healthcare and economic recovery appealed to some voters across faiths, including that 20% of white evangelicals.
Your invocation of 1 Corinthians 4:6 and 2 Thessalonians 2:3 seems to suggest that deviations from conservative voting indicate apostasy or "thinking above what is written." From a Catholic viewpoint, this misapplies Scripture. The Church teaches that conscience, informed by faith and reason, guides moral decisions—including voting—not rigid partisan alignment. Catholics aren't "liberal" as a monolith; we're diverse, with conservative voices (e.g., on life issues) voting for Romney, while others prioritized the common good in ways that led to Obama. The idea that "only a minority of Evans voted like Catholics usually do" overlooks that overall Catholics were nearly split (50% Obama, 48% Romney), reflecting thoughtful discernment rather than decline.
Finally, the link you shared (peacebyjesus.com) appears to compile stats to argue evangelicals are superior in conservatism and faithfulness, but such comparisons often cherry-pick data and ignore context—like higher Catholic church attendance in some surveys or the Church's global role in promoting justice. Faith isn't a competition measured by polls; it's about living the Gospel. If evangelicals are declining in conservatism as you note, perhaps we can agree that's a challenge for all Christians, calling us to unity rather than division.
