This ol' geezer also voted for Clinton. I too became increasingly disappointed with the tone of Clinton's campaign. I believe they are both great candidates but I became concerned in the choices Clinton made in her staff and strategy and whether such mistakes (in my opinion) would carry over into her presidency.
More to your point, I think the Super-duper Tuesday experience in California serves a valuable lesson in the flawed concept of running with the pack. California should break from the pack and slide the next presidential primary back toward the original date.
