I've begun reading Dexter Filkins' profile of Marco Rubio in the Jan. 19 issue. I mention this because I want to call attention to the second paragraph on page 26. The direct quotations in that paragraph are capitalized--or not capitalized--the way I was taught to do it, and the way I still feel is correct. Here's an example from that paragraph.
"Trump boasted of 'an assault like people have not seen since World War Two,' and said, 'We're a respected country again. ...'"
The first quotation in that sentence is not a complete sentence, so "an" is not capitalized. The second quotation is a complete sentence, so "We're" is capitalized.
