Not true. Progressives are more likely to stay married than conservatives. And progressives dads are more likely to help with child rearing.
And fake/phony progressives are 99.336% more likely to make shit up. 
Look it up. The states with the highest divorce rate and highest teenager pregnancy rate are all conservative.
The biggest effect on children I have seen between having and not having a father around the home is that girls are less likely to become teenage mothers when there is a father around.

Single parent, families are a foundation of progressive votes. Let's keep it that way.
