1. As concerns the first point: Romney may well have been listed as CE of Bain, but for other reasons not engaged in the operations of the firm. As an example: My commander went on leave and the executive officer filled in. The commander was still the commander, but the executive officer was acting as commander in his absence. Granted it is a different ballgame in the military, but Romney's story is a close parallel. Naturally, the Obama-ites are going to make much of the "discrepancy".
2. It is my understanding that wealthy office holders usually place their holdiings in a blind trust to avoid the appearance of conflicts of interest. I have no cites as to a legal requirement, though. If Mr. Romney has done so, then he has no direct control of his assets and they are being controlled by his agent. Again, I do not see a problem with this. If he has been made aware that his agent has made some questionable investments, then I would expect him to fire that agent and get another one.
3. Although I have serious misgivings about Mr. Romney, my misgivings concerning the present office holder are far more serious and far more wide-ranging. And to be perfectly, frankly honest, only Mr. Romney or Mr. Obama have the chance of a gas can in Hell of being elected.
4. Who am I going to vote for? Take a SWAG at it.
