Liars, Demogogues and Ignoramuses

Der Spiegel, via Mark Thoma:

They lie. They cheat. They exaggerate. They bluster. They say one idiotic, ignorant, outrageous thing after another. They've shown such stark lack of knowledge -- political, economic, geographic, historical -- that they make George W. Bush look like Einstein and even cause their fellow Republicans to cringe.
"When did the GOP lose touch with reality?" wonders Bush's former speechwriter David Frum in New York Magazine. In the New York Times, Kenneth Duberstein, Ronald Reagan's former chief-of-staff, called this campaign season a "reality show," while Wall Street Journal columnist and former Reagan confidante Peggy Noonan even spoke of a "freakshow."
That may be the most appropriate description.
Tough times demand tough and smart minds. But all these dopes have to offer are ramblings that insult the intelligence of all Americans -- no matter if they are Democrats, Republicans or neither of the above. Yet just like any freakshow, this one would be unthinkable without a stage (in this case, the media, strangling itself with all its misunderstood "political correctness" and "objectivity") and an audience (the party base, which this year seems to have suffered a political lobotomy).

Why does it take German media to point out the obvious?  Why won't the so-called liberal mainstream media just say, "You guys are ridiculous clowns?"
