I just looked at the numbers again.
There were a little less than 130,000,000 TOTAL votes cast. TOTAL.
Of that 130 million, 54% called themselves Protestants. The real number would be higher because many Protestants do not use the term “Protestant”, preferring to be called “Christians”. No matter what, 54% of that 130 million is just over 70,000,000.
Of that 130 million, ONLY 27% were Catholics. That’s 35,100,000.
Therefore: Of the 70 million Protestants, we know that 45% voted for Obama = 31,590,000.
Therefore: of the 35 million Catholics, we know 54% voted for Obama = 18,900,000.
Thus 12,960,000 more Protestants voted for Obama than did Catholics.
Thus, Protestants put Obama in office.
Feel free to refute what I have said. All the numbers are freely available on the internet at reputable sites.
Just remember, 12,960,000 more Protestants voted for Obama than did Catholics. Actually the number maybe millions higher than that.
A brief scan suggests that the Baptist and LDS are successful in turning out conservative voters.
Religions which dominate a county (the dot in each county) ought to be turning out strong socially conservative voters. Where they are not, e.g. South Texas, there's work to do with a good chance for success, i.e. getting their members to take their religious beliefs seriously (pro-life, anti-gay marriage, etc.)
