Note that McCain’s fundraising totals in 2008 were closer to Ralph Nader’s (who I just found out was a candidate in '08) than they were to Obama’s.
In any case, who’s to say that the political donations of faculty are an accurate indicator of the faculty’s leanings. The numbers involved are small enough that a single Democratic bundler could easily account for the 82:1 skew.
Even if that’s the case, I wouldn’t want to attend a school where professors can’t take a competing viewpoint seriously. I’d still be cautious about political essays, but I doubt Stanford is a bastion of intolerant Democrats, Republicans, Know-Nothings, Whigs, Democratic-Republicans, Free-Soilers, or any other political movement you care to name.
