Sean Hannity’s “Great American Panel” last night was anything but. Epitomizing America — if I can interpret the name — were cacophonous guests Rev. Al Sharpton, rocker Meat Loaf and Minnesota Rep. Michele Bachmann, who had a shoutathon about government stimulus packages, “angry and mean” rap and heavy metal, race in the “age of Obama,” school spending and why African Americans tend to vote for Democrats. Net sum: For once, Bachmann doesn’t come across as the nuttiest of the bunch. The competition there is fierce.
