If you read what the man actually said he isn't very focused on slamming Nathalie Portman.
He's making a reasonable point about what ideals we want for people and how the reality of a famous person like Portman is very different from that of average poor people. You can disagree with the point and so on, but it's hardly a gaffe. If anything, I suspect it's positive political move because he gets out an issue that he wants to be out there.
There is a reasonable argument that in a society where most children grow up with two breadwinners, growing up just one would have an adverse effect on the child. However by speaking specifically about Portman to whom the above would not apply because she will be raising the child with the father. What he is doing is making it seem as if his religious convictions against premarital sex and children out of wedlock are really an economic one, when often, like in this case, they are not.
And then there is this quote:
The assertion that most children to single mothers would starve to death without government assistance is:
1. Ludicrous
2. if it were true, would be a great argument against the conservative position that the government should not get involved in welfare and should leave it up to private charity, if he really believes this, than he should be attacking economic conservatives on this.
the part about Undereducated is phrased in a way that makes it hard to statistically quantify but it isn't as if most single parent mothers are high school dropouts, in 2008
15.5 percent hadn't graduated from high school, while 26.9 had an associate's degree.The part about very poor could be somewhat subjective but
considering 24.6 are below the poverty line saying most are very poor is a exaggerating things.
The part about "can't get a job' is quantifiable Huckabee is simply wrong only 18.7
didn't have a job in 2007, and while i'm sure that number is up since then there is no chance it's over 50% now.
And I can't remember seeing single motherhood being glorified, what I have seen is single mothers being commended with the hard work they do in raising their children but that always includes saying how hard it is to raise a child on your own.
