RUSH: After he graduated from Oxford over in the U.K. “Mayor Pete” Buttigieg spent a few years as a consultant for McKinsey & Company. It’s a big corporate consulting firm. The liberals call him “Wall Street Pete.”

Senator Elizabeth Warren, a rich former corporate lawyer herself, has been pushing Mayor Pete to tell everybody what he did and who his clients were. So last Tuesday, Mayer Pete finally did. His list includes: Blue Cross/Blue Shield of Michigan, Best Buy, the EPA, the Department of Energy, U.S. Postal Service, and the Department of Defense. Mayor Pete said he didn’t think his consulting work led to any job cuts. But to appease the Democrat base, Mayor Pete slammed McKinsey as “amoral.”

Now some seasoned Democrats are worried. They’re afraid these anti-corporation “purity tests” are gonna hurt Democrat candidates. They’re panicked that Republicans will accuse Democrats of “waging a war on prosperity.”

Former Chicago Mayor Rahm Emanuel points out that when they’re fighting over who’s more anti-corporation, Democrats are not explaining how they’re going to grow the economy because they can’t, they don’t.

Rahm, you and your fellow Democrats are anti-corporation. You are anti-business. Your party has been waging a war on prosperity for decades. Except when it comes to your own prosperity, which is what you’re all about.

Finally, the Democrats are exposing each other for what your party is really all about. And you’re right to be worried about all of that. Keep it going, as far as I’m concerned.
