I found this interesting Tweet from Hannah Sampson, business writer for the Miami Herald:

@mkramer I like no candidate on Facebook (per my newspaper’s policy) but someone decided I liked Mitt Romney and hacked my page to say so.
Journalists are often prohibited by their media employers from publicly displaying their political beliefs in order to maintain nonpartiality (or the illusion of it, anyway). That Sampson would have made herself a fan of Mitt Romney’s Facebook page is quite unlikely indeed.
