Sarah Palin urged her Twitter followers last night to read an op-ed column that warns the United States could be on the road to Nazi-like tyranny.

"This is about the rule of law vs. an unconstitutional power grab. Read Thomas Sowell's article," she wrote, with a link to the piece in Investors Business Daily.

In his article — titled, "Is U.S. Now On Slipper Slope To Tyranny?" — Sowell warns that Obama's pressure on BP to create a $20 billion escrow fund is reminiscent of Hitler's actions:

...during the worldwide Great Depression, the German Reichstag passed a law "for the relief of the German people."

That law gave Hitler dictatorial powers that were used for things going far beyond the relief of the German people — indeed, powers that ultimately brought a rain of destruction down on the German people and on others.

If the agreement with BP was an isolated event, perhaps we might hope that it would not be a precedent. But there is nothing isolated about it.
