Do you think it's possible that they think that Mccain will just cause more problems? So that makes them want to donate more money to Obama because they see him as someone that will correct problems instead of create them.

The reason I see it like this is because it is all DONATED money. It's not like anyone twisted there arm and told them that they need to give money to Obama. It's completely voluntary and any "drain" on the industry it might do is by personal choice of the industry. Perhaps if they thought Mccain was the right choice, then the figures would be reversed. I bet Mccain supporters wouldn't be complaining about it if that were the case.
