Answer the specific points in the article.
The problem is that the Florida constitution is poorly drafted. Keyes is right--there is a portion of the Constitution that reads as he says it does--Art. I, Sec. 2, I think.
But read on: Art. I, Sec. 9 states the following: "No person shall be deprived of life, liberty or property without due process of law..."
The two sections are clearly contradictory--Section 2 appears to state a blanket prohibition: all persons have a right to life--but then Sec. 9 clearly contemplates the state taking away life and liberty, which we know happens all the time--I'm sure Florida jails and prisons are packed with folks who have had their liberty rights taken away by the states, and the Florida cemetaries have a number of folks who were executed by the state, clearly taking away the "inalienable" right to life.
Unless Keyes wants to go around arguing that Florida should open its prisons and pardon all its death row inmates, I don't think he makes a very strong case, because Section 2 has to have the words "without due process" read into it, otherwise it ceases to make any sense.
I'll answer the only point that really needs to be addressed. Keyes is confused on what supreme executive authority means. It doesn't mean that the governor has the supreme authority in the state as Keyes has either misread (which I doubt) or twisted (bingo) it to mean.
What it means is that Keyes is the supreme executive authority, ie the highest office in the executive branch. Likewise, the FL assembly has the supreme legislative authority, and the FL SC has the supreme judicial authority. What Keyes isn't telling you, is that the supremacy of the governor as the supreme executive, in no way diminishes the powers of the other branches of government. It's not a monarchy Alan, period.
