^^^ Those findings are based on a survey of college seniors. Even ignoring that, I don't think the results agree with the conclusion that "moderate men may be the least likely to make a positive difference."
In a lot of cases, I'd suggest that both moderate men and women are likely to be less political or perhaps just more focused on pragmatic aims like graduating college, student loads, potential job prospects, getting laid, etc. This article kinda seems like another attempt to equate moderation with conservativism and goes on to enforce the ridiculous purity test that's required to be a "real" liberal.
