Same place you're pulling your comments on Jews.Where did you pull that stat from?
But probably not far off based on population make up in the US. It's simple, Christians make up a far greater percentage of the US population therefore they must also make up a far greater percentage of liberals. It's not a condemnation or accusation, it's just how it works out when dealing with a large population that has a large percentage of any single attribute. A quick search put Christians at 70.6% of the population and Jews 1.9%, so my 1 in 4 is actually being overly generous. Religion in America: U.S. Religious Data, Demographics and Statistics
I'll also point out that generalizing any ethnic group is the very kind of group politics/division that the libs are pushing.
This is getting too far off topic, even for NES, If you'll let this go, so will I.
