You may be on to something with the phase II of Operation Chaos in your post. One of my good friends at work is a hard core conservative. Today he told me he donated $50 online last night to Hillary's campaign--for the express purpose of helping to prolong the Democratic slugfest. I'm thinking about voting for her in the May 6 Indiana primary for the same reason.
