Due Process is not the same as the Due Process Clause 

I saw that you undid my edit. A couple of things.

First, the funny one. It seems that you undid your edit as well, with  20:32, 11 February 2012. Dunno if you meant to do that since your edit title mentions something else.

The other is that if you look at the other Clauses mentioned, Citizenship Clause and Equal Protection Clause, their links are Citizenship Clause and Equal Protection Clause rather than Citizenship and Equal Protection. Parallelism argues for Due Process Clause.
