Personally, I think this is an idiotic statement.
The DFLA, Democrats for Life of America, is a league of Democrats who are decidedly pro-life (from womb to tomb), advocating for not only pro-life policies regarding abortion, but are also advocates for policies relating to universal health insurance, anti-poverty measures, paid parental leave, living wage, abolishing the death penalty, anti-euthanasia, and that are pro-environmental conservation.
While they are a minority within the Democratic Party, they are present. They made their presence known with the ACA. The DFLA drafted the 95/10 Initiative, a series of legislative actions that are designed to reduce the abortion rate by 95% within 10 years of implementation... without even banning abortion. These initiatives are designed to address the issues that women face when confronted with a crisis pregnancy. Several of these policies were put into the Pregnant Women Support Act and were eventually written into the ACA. It truly was one of the greatest advancements of pro-life legislation within two decades. Yet because it was done by Democrats, it wasn't reported on through the conservative news media. And since the leadership of the Democratic Party is presently Pro-Choice, it wasn't really talked about in the liberal media either.
I think this guy needs to wake up and realize that many Catholics, mainline Protestants, Jews, and others are deeply religious, value life, and still identify as Democrats for various reasons. In fact, when asked if abortion was "morally wrong", 1 in 3 registered Democrats agreed that it was. And when it came to being asked if abortion should be safe, legal, and rare... 2 out of 3 agreed.
So, among voters registered as Democrat, abortion still isn't viewed as being a positive thing, even among those who are pro-choice.
