I think this is overly optimistic. It assumes that politicians don't understand that what they're doing will likely become public knowledge.
That seems excessively generous, and suggests that these people are actually ignorant of the scrutiny under which their actions can and likely will be placed. I don't think that's likely, at least in most cases, if not all.
It seems much more likely to me that these people simply don't care what their constituents think. Perhaps that's not something people in the EU are accustomed to, but Americans have been enjoying this phenomenon for generations. Perhaps our lobbyists are just spreading this problem like a political plague; if you think of it that way, they're our own ship full of infected rats.
Sorry, guys. We don't want them here either, but we didn't intentionally send them over there (or, at least, we didn't vote for it).
