A moot survey.  There are as many definitions for "Christian" as there are humans in the galaxy.  Even Barack Hussein claimed to be a Christian while slaughtering Afghans, Pakistanis, Syrians and various other innocent beings.  And don't forget Fast & Furious gun running to MX that got an American border patrol officer murdered.

According to a 2014 study by the Pew Research Center, 70.6% of the adult population identified themselves as Christians, so a big DOH to "70% of women who had an abortion ID as Christians."
