Because the Democrats "Believe in" Government:

During the Bush years, we constantly heard the refrain, pushed especially by Paul Krugman, that the government was doing incompetent and corrupt things because conservative Republicans "don't believe in" government. Put the government in the hands of true-believing liberal Democrats, and incompetence and corruption will virtually disappear.

This always struck me as foolish, in part because the problems with government competence and integrity are structural, not individual, and in part because it required one to believe Krugman's fantasy that the Republican elite during the Bush years was dominated by wild-eyed libertarians intent on drowning the government in a bathtub, or something like that.

Anyway, here's the latest example of competence an incorruptibility from our liberal Democrat elites:

The Food and Drug Administration said Thursday that four New Jersey congressmen and its own former commissioner unduly influenced the process that led to its decision last year to approve a patch for injured knees, an approval it is now revisiting.

The agency's scientific reviewers repeatedly and unanimously over many years decided that the device, known as Menaflex and manufactured by ReGen Biologics Inc., was unsafe because the device often failed, forcing patients to get another operation.

But after receiving what an F.D.A. report described as "extreme," "unusual" and persistent pressure from four Democrats from New Jersey — Senators Robert Menendez and Frank R. Lautenberg and Representatives Frank Pallone Jr. and Steven R. Rothman — agency managers overruled the scientists and approved the device for sale in December.

All four legislators made their inquiries within a few months of receiving significant campaign contributions from ReGen, which is based in New Jersey, but all said they had acted appropriately and were not influenced by the money.

UPDATE: It's amusing to get accused of anti-Democrat "partisanship" in the comments for a post whose theme is that when given power the Democrats are just as corrupt and incompetent as the Republicans.
