Observations: “It shouldn’t surprise anyone that family structure is so controversial. The family, far more than government or schools, is the institution we draw the most meaning from. From the day we are born, it gives us our identity, our language and our expectations about how the world should work.

That is why social engineers throughout the ages see family as a competitor to, or problem for, the state.” —Jonah Goldberg

Village Idiots: “The City of Chicago is a good illustration of why allowing local jurisdictions to put in place these gun safety laws doesn’t work. Because it’s just too easy for those with bad intentions to just cross the city line or just cross the county line and make a handgun purchase that they are prevented from making in some other jurisdictions.” —Josh Earnest

Late-night humor: “Analysts say Bernie Sanders has shifted his focus to more aggressive attacks on Hillary Clinton. In fact, Sanders is planning to go after her emails as soon as his granddaughter explains to him what an ‘email’ is.” —Conan O'Brien
