Goldman Sachs may have given $994,795 to Obama, but they also contributed $230,095 to McCain. Citigroup was $701,290 and $322,051. JP Morgan was $695,132 and $228,107. UBS AG (a Scottish bank?) gave $543,219 and $192,493. Morgan Stanley was $514,881 and $273,452.
The US Government may have given $494,820 to Obama, but they also gave $208,379 to McCain plus the US Army gave McCain $167,820 and the Defense Department gave him $144,105. This looks like McCain actually got $520,304 from the US Government when you count in the military.
I don't know what all that means, but it does look like the academic community was overwhelmingly for Obama (no Surprise).
I think they were hedging their bets. Were I a corporate head, I would donate something to each to stay on friendly terms. The amount would be proportional to the probability of their success.
Then I'd say I was just helping to keep democracy alive.
