The Left's unhealthy Koch habit

John Hinderacker at AOL and RCP:

On the surface, the Koch brothers would seem unlikely targets for the political left. After all, they patronize the arts, favor gay marriage, support legalization of drugs and advocate reduced spending on defense.

But they also have a unique distinction: They are two of the very few billionaires in the country who actively contribute to libertarian and conservative causes. Consequently, many liberals have engaged in what can only be characterized as a vicious campaign to drive them out of public life.

You know what to do.
