Fair and Balanced: Mark Sanford is a Democrat?
Fox News falsely identified Mark Sanford as a Democrat. The cable news network later corrected their mistake. This isn't the first time Fox News mistakenly labeled a Republican a Democrat. For instance, Mark Foley was labeled a Dem when news broke of the page sex scandal.
Fox News is either too incompetent to fact-check Sanford's and Foley's party affiliation or they willfully continue to misinform their audience. You decide. Either scenario does not speak well for the journalistic quality of Fox News.
