Also:   "Maybe he just found another candidate he liked better."

For once you have stumbled across a fact.    Now if you only read what you yourself have written, you may start to understand.    Yes, he found he liked Obama better.   Why?   Partly because he realized Hillary was a sinking ship.   The point is, a rich person can seek to influence the outcome of an election--but only by picking a candidate who already has much to offer to the electorate in general. And far from "buying" a president, the rich person has to guess which candidate would be the strongest, and support that person--and be willing to change if he or she guesses wrong.

In that respect it's actually very close to making up a harmony to a song you've never heard before--you make an educated guess as to where the song is going--but be ready to change immediately if you guess wrong.

In fact a lot of corporate sponsors support both Republicans and Democrats--so they won't be out in the cold no matter which party wins a given election.

And yes, contrary to another cynical view fondly held by some Mudcatters, there is in fact often a difference between the Republican and the Democrat on a given issue.
