It's eminent domain, not imminent domain.

It's one of those things that was written into the Constitution, but not by name, which I find to be the smarter way. Things mentioned by name but not by definition are impeachment, "questioning" of Congress members, imposts, duties, excises, naturalization, securities, felony, letter of marque, militia, writ of habeas corpus, bill of attainder, ex post facto law, natural-born citizen, "the" recess of the Senate, misdemeanor, good behavior, equity, corruption of blood, republican form of government, convention (for proposing amendments), common law, and, worst of all, war.

Without a definition included, there's a danger that either the meaning can change (as indeed habeas corpus did over the course of a few centuries before the Constitution), or that a provision can be circumvented by changing a name, such as by calling a war a police action.

A caller brought up something interesting. I couldn't figure out what he was trying to say, but he mentioned the requirements for impeachment and removal of the President, and for overriding a veto.

It is odd that the requirement for removing the President from office is only 1/2 of the House and 2/3 of the Senate, while merely overriding a veto requires 2/3 of both houses. I'll have to think about that one.
