The responsibility of citizenship is a simple principle
Your arguments wander all over the place as you try to evade its existence. [eg: citizens not responsible any more because of a vote in congress???]
To answer your question about candidates, I am trying to avoid looking at the primary race. Nothing makes a candidate look uglier than being a member of one of these packs. It is a long time before I get to cast my vote on the subject.
All I can tell you for sure is that in the primary, I will vote for one of the democrats. In November all bets are off, though Anyonebutbush sounds pretty good right now.
