Casino mogul Sheldon Adelson is giving $10 million to the 2012 election efforts of the Koch brothers, a Republican Party insider in Nevada confirms.

This brings Adelson's total 2012 spending to a mind-numbing $46.5 million: $16.5 million went to Newt Gingrich's Super PAC (some of that was donated by his wife), $10 million is going to Mitt Romney's Super PAC, $10 million is going to Karl Rove's Crossroads group, and now another $10 million is going to the Koch Brothers.

But while spending nearly $50 million might seem like a lot, Adelson isn't done trying to buy the election for Mitt Romney and the Republicans: He's said the amount he expects to spend is "limitless" and could easily exceed $100 million. As absurd as that figure sounds, Adelson isn't bluffing: He's one of the 15 richest people in the world and could easily spend $1 billion if he wanted to. And the only people that happier about that news than Mitt Romney are the media consultants who will take their 15 percent commission on the ads his millions buy.
