Two points. First, your title is dishonest, insinuating that this study is considering tolerance broadly when it is, in fact, quite narrowly focused on voters' attitude towards one religion, Mormonism. Second, I'd love to see the methodology behind this study, something Fox conveniently neglects to link. Without such details, it's impossible to determine how much credibility the study deserves. I will say there's a huge difference between posing that question in the abstract, in 2007, vs. posing it today when respondents will tend to conflate Mormon with Mitt Romney.
