"I don't believe NSA blackmail can or will happen in general, for reasons I have mentioned before here on HN. One of the most common kinds of comments here on Hacker News about issues like this is a comment that ASSUMES that if government leaders are under pervasive surveillance they are all afraid of blackmail."
First of all, having being part of the action arm of the government (Marine Corps) I can say from experience that I don't trust any of the fuckers in DC, and I think your attitude is naive. Secondly, you are setting up a strawman fallacy by saying that the comments you most frequently see assume that if leaders are being watched they are all afraid. I haven't seen that claim made anywhere, even on conspiracy websites.
No, control is about a toolbag, and some tools work on some people and some tools work on others. Just like if you were trying to recruit a spy to spy on his country for you. Maybe blackmail works on person A, but maybe person B just wants his kids to go to a good US college. Maybe person C just needs some money. Not all the politicians needs to fear surveillance blackmail because there are other methods for those who don't succumb to that particular tactic.
"The simple fact is that there is value system diversity in the United States electorate, and there is personal conduct probity variance among United States politicians,..."
More strawmen. What does "probity variance" even mean? Probity means completely honest, so how can there be variance on being completely honest? Not to mention even saying the word probity in a sentence targeted at US politicians falls flat on the face of history.
"and there isn't any universal way to unduly influence politicians merely through even the most diligent efforts to discover personal secrets"
Nobody is saying there is a universal way to compromise or unduly influence politicians, as per my previous statements. The fact that you are ignoring all the other ways to unduly influence them seems striking, especially given your own claimed position as a judicial clerk for your states supreme court. Either you know about them and are omitting them on purpose, which is dishonest conversation (I'll refrain from lawyer comments), or you don't, in which case you are out of your depth in your commenting. All I see in your statements is a string of logical fallacies with no substantive comment of any note. (your first paragraph excepted)
Also, regarding the idea that there are a handful of straight arrow politicans. I don't disagree entirely, though I may question how straight, but I think you might misunderstand their power position in the beltway. They may be upright, but if they sit back and don't do anything about the egregiously unconstitutional acts occurring around them they are guilty by association.
