I feel your pain. I'm a handful of years from retirement, my BP is creeping up and I am considering chucking politics also. It's always been my observation that people don't want to know the truth, especially about those to whom they entrust so much. Strange.
Delay your decision for a while. It’s not clear if McCain won anything. Be patient for a week or 10 days. Then decide to make a decision. Romney could pull it off. Those other idiots must drop out. Just wait.
