When the Mitt Romney race is over one thing more than any other will probably define it: billionaires.

The Romney campaign is just lousy with them. On Thursday Forbes reported that the latest player, billionaire Vegas casino mogul Sheldon Adelson, has vowed to spend $100 million dollars of his own money to get Mitt Romney elected. Possibly even more. He will do 'whatever it takes' to defeat Obama, he told Forbes.

Sheldon Adelson is the seventh richest man in the U.S. and the fourteenth richest man in the world. On the 'World Billionaires' list, he's just a hair behind Tea Party shadow leader David Koch.

'No price is too high' to protect the U.S. from what he sees as Obama’s 'socialization' of America, as well as securing the safety of Israel, Adelson says. Adelson, 78, added that he considers this to be the most important election of his lifetime.

When you're that rich you have a lot of pearls to clutch, I guess. Wouldn't you know Adelson was a huge Scott Walker backer during the Wisconsin recall (he sent a cool $250,000 Walker's way). Adelson loathes unions, any unions, apparently.

Among the highlights of an article called Why GOP Mega-Donor Sheldon Adelson Is Mad, Bad and a Danger to the Republic, Rolling Stone wrote: 'Adelson told the Wall Street Journal radical Islam and the right to more easily join a union were the two most 'fundamental threats to society.'

Rolling Stone added: 'He usually ambles around with an armed former agent of the Mossad, Israel's spy agency.' And another illuminating nugget was: 'Sheldon Adelson simply loves to sue – over 150 lawsuits in Clark County in ten years alone, including against his own sons.'

On March 22 Adelson hosted a dinner at his home that was stuffed with Mitt Romney supporters, including the RNC chairman with the name that suggests he was always going to be RNC chairman, Reince Preibus.

$100 million dollars can buy you clout. You may even be able to buy a presidential election with it. This is the brave new era of the Supreme Court's Citizens United verdict after all, when billionaires can effectively drown out everyone else's voice and Supreme Court justices themselves can shout 'You lie!' at the president.

In this brave new era Romney's candidacy is being defined by wealth, and by blatantly political rulings in his party's favor, and that's why there are untapped millions in cold hard cash just waiting to be spent in that mission. It's David and Goliath, with plutocrats.

That's why I wouldn't make a $10,000 bet on live TV that Romney can't go all the way now, with that kind of backing. Robber barons and rich men usually get what they want. And they don't sink $100 million without the certainty of a return.
