I took a political science course on Varieties of Capitalism last semester and greatly enjoyed the subject material; although I'm a biology/public health double major, I'd say that Varieties of Capitalism was one of the most influential courses I've ever taken. I went to the professor's office hours a couple of times to discuss history and political economy, and I've been thinking about asking him for an LOR. However, I chickened out after the midterm and switched my grading option to pass/no-pass, and I would've gotten an A- in the class had I taken it for a letter grade. Given that the professor will almost certainly see my transcript (I mean, it's standard practice for recommenders, after all) and notice the P grade if I ask him for an LOR, should I bother to ask? Would the grade be an issue?
