Neo dai, I'm not a student of politics but I do know for the fact what am saying unlike you being so emotional and blindly ignoring/defending the facts about bernie. Not that it's a big crime but one who has been saying that he wouldn't take donation from billionaires, it does raise eye brows when sites like opensecret has to reveal things about him.

"Per individual donation limit to federal candidate is $2700.

Federal contribution limits.
Federal law restricts how much individuals and organizations may contribute to political campaigns, political parties, and other FEC-regulated organizations. Corporations and unions are barred from donating money directly to candidates or national party committees."

So yes, that "individuals" is a PAC. As I've written in earlier post above, it's a committee of corp individuals.

Could you do little research before you write? It just proves you are very emotional and impulsive(saying things without thinking).
