Investing in the friends of Presidents...

[Belok]

I know I'm not as informed about investing as most of the people who participate on this forum - but this seems like a topic of importance, and I'd like to see if you more experienced investors have any input...

Basically, my question is - Wouldn't it be a no-brainer to invest heavily in companies who are run by friends of the current/upcoming president? Or any well-run businesses that involve the Presidents' field of expertise?

I know it's easy to use hindsight and say "Bush wanted to be an oil tycoon, we all should have invested in oil companies the second he was elected!" - This is why i'd like the opinions of some of you veteran investors. I am not old enough to have known about Clintons business relationships before his presidency - or if their profits increased after he was elected.

But from a novices perspective, it seems extremely obvious that a President will make favorable laws + government contracts to his friends and other experts in that field.

For example...if Giuliani were elected in 08, should we expect business as usual(massive growth) in the oil industry?

Can this be historically proven?

Ty for your input.
