Fox Misidentifies Sen. Arlen Specter as a Democrat.

From Media Matters:

"On the July 24 edition of Fox News' Special Report with Brit Hume, on-screen text identified Sen. Arlen Specter (R-PA) as a Democrat during a report from chief Washington correspondent Jim Angle about Attorney General Alberto Gonzales' July 24 testimony before the Senate Judiciary Committee. The text appeared during footage of Specter telling Gonzales that the committee would be reviewing his testimony about a May 10, 2004, confrontation over the Bush administration's warrantless domestic wiretapping program to "see if your credibility has been breached to the point of being actionable." Angle introduced the footage of Specter as an example of "other[]" senators who "urged the attorney general to correct his testimony, vaguely warning of legal action." At no time during Angle's report did anyone say that Specter was, in fact, a Republican."

Apparently this is not the first time they’ve done this. Is it deliberate or are they just incompetent?
