One question:  are you SURE that was actually Cornyn responding to you and not some staffer?  I believe it is true that even Ashton Kutcher has turned over "his" Twitter account to "his people" after his posting about the Penn State sex abuse scandal.  The Senator does not strike me as one who would be all that technologically able - if you know what I mean.

But, your point is still well taken.  There is no sense of respect in Washington any more, in great part because our elected officials no longer see themselves as statemen (or would it be statepeople) today.  Instead they are constantly running for re-election.  Part of this may be because of all of the money they must raise to run for office - they have to be constantly fund raising and thus constantly campaigning...thus there is no longer anytime to co-operate with the other side if you are constantly running against them.  I offer this not as an excuse, but merely an explanation - and a step toward a solution.

Given that, I wonder if the Cornyn Twitter account isn't run by a staffer or worse someone on his re-election staff?  Any idea?
