You assume he lost and that the presidency was his goal.
If you have $350 in your pocket right now, you’re driving to work and you decide you are REALLY thirsty, What to you do?
Stop at the quickstop and spend $1.50 on a Pepsi. Because you can.
If you have $350,000,000 in your bank account and decide to help your buds play power games with the planet, you spend a couple million to make it happen for entertainment.
Because you can.
Your wealth analogy has a lot of holes in it. But even if the wasted personal wealth was not an issue, why would he spend months and months of campaigning round-the-clock and dragging his family and others through the same if he didn't want to win anyway.
You know that if you're right, I would have even less respect for Romney and I don't have much currently. He would have to be a total thoughtless, self-centered creep to solicit money and effort from so many people if he had no intent to try and win. Such deception would be disgusting and blatantly dishonest.
