Could be. Doesn’t bother me. Over the years, a fair number of presidents have had school age children. Offhand I remember the Kennedy kids, Amy Carter, Chelsea Clinton, and now the Obama girls. Can’t think of a recent Republican case, but that’s immaterial.
Children are a good thing. IMHO, if a president has young kids, we should not begrudge sending a security detail on school trips. Even to Mexico.
Most school kids get one foreign vacation trip a year, if their parents can afford it.
How many foreign countries have the obama girls been to in the past three years? The obama daughter should have given her spot to some needier child and spared us paying for the SS. The school should have picked a safer place to vacation.
