The big bankers, hedge funds, and other institutional players pretty much all hate Obama and his hacks, even though most of them gave him millions and helped him get elected twice. Buyer's remorse.
If the big banks actually controlled all of the politicians, you'd see just a few guilty / negligent individuals get fined millions, terminated, imprisoned, etc - not the bank get a $5 billion fine. Dimon, Blankfein, Stumpf, Weill - they'd all rather Romney would have won in '12. Buffett has even taken to speaking out against the Obama admin recently.
Not sure about bankers wanting to rig the big lotteries via hackers because they hate seeing the poor and middle class come into money. That's the first I've heard of that.
