We have to remember in that Bloomberg poll, strong Republican support for [Donald ]Trump's proposal, but the country at large - strong opposition to that support.

I would say that the one incredible thing that Karachi has going for it is the unabated supply of new migrants that pour into it day after day. It could be a poor factory worker who simply wants a job, it could be an ambitious guy coming for an education - they all add hope and vibrancy to the city. Now, this is not something that is generally taken as positive in Karachi. But the hope is that the migration that comes into the city replenishes its stores of resilience and energy.

President-elect [Donald] Trump has made a provocative choice for secretary of education. Betsy DeVos comes from a wealthy Michigan family. She is an advocate for school choice. That phrase means, in essence, directing public education money to charter schools, private schools or parochial schools.
