Avoid blindly changing capitalization 

An editor recently used the AWB tool to change a bunch of capitalizations in a way that hurts the article.  I undid his edit.  There are probably a few things that need to be lowercased but they will require case-by-case analysis.

While there is some capitalization that could be changed without controversy, there is some which clearly should be kept capitalized and some which may be debatable.

Note:  In the "rules" listed below, I'm assuming the rules of capitalization haven't changed significantly since the 1930s, and that we can rely on the capitalization used in Amendment XX as a guide.  If this is false then let me know and I'll strike everything that follows.

Cases where capitalization should be copied verbatim:
The text of Amendment XX should be copied verbatim from accurate transcripts.

Other cases that clearly need capitalization:
Any form of Congress, President, Senator, etc. which is being used in the article in substantially the same way as it is being used Amendment XX, where it is capitalized in the Amendment (other than at the start of a sentence or any other place where any word would be capitalized).

Other cases that clearly do not need capitalization:
Any form of those words that do not specifically apply to offices or officeholders of the federal government of the United States of America.
Any form of those words which is being used in the article in substantially the same way as it is being used Amendment XX, where it is NOT capitalized in the Amendment or where it clearly would not be capitalized but for the fact that it appears at the start of a sentence or or any other place where any word would be capitalized.

Other cases that may require discussion (or which may fall into one of the above categories - I'm going to plead grammatical ignorance here):
Forms of those words which are ambiguous as to whether they are specific the United States federal government or not and which it is unimportant to make the distinction.
Any form of those words which is being used in the article in substantially the same way as it is being used Amendment XX, where it is capitalized because it is at the start of a sentence or any other place where any word would be capitalized, and it's unclear if the word would be capitalized but for that fact.
Forms of those words where they clearly apply to the federal office but the use doesn't map directly to the use in Amendment XX (this is the case where I'm unclear on the rules of grammar).
