Politics – effects of Super-Pac Money on choices for political candidites?

I have the basic idea of what Super-Pacs are, but i’m having some trouble with the details and research etc.

Basically, what are the “effects of Super-Pac Money on choices for political candidites?”
in fair detail, rather enough to write a reasonable sized paper on it

Looking for about 3 effects of something along those lines
