If I were the campaign. and though I know they promised a book bomb in NO, I'd save those books and use them in Iowa which is basically where all campaigns start., or where candidates seeking recognition that they are seriously going for it start out. I'd pick two or three of the most heavily populated area's , locate the days and times of their heavily attended festivals and set up tables, maybe find their largest manufacturers and hand out the books when people are leaving their jobs, aim to attend events where there are a lot of veterans in attendance even. Just some idea's to use the books more constructively to gain notice as a contender.
