As I wrote earlier, the typical Republican presidential candidate has no real hope of getting the nomination, let alone the Presidency.

But this article from the Wall Street Journal makes it plain that they are still quite rational to pretend.

Republican presidential candidate Ben Carson and his wife, Candy, earned between $8.9 million and $27 million in a recent 16-month period, largely fueled by book royalties, speaking engagements and Mr. Carson’s service on the board of directors for two big companies.

When it’s worth this kind of money just to be this TEA party kind of famous, you’d be kind of crazy not to.
Not that Carson isn’t a few other kinds of crazy.
