Billionaire investor Warren Buffett will be introducing Hillary Clinton at a Nebraska campaign event Monday -- an effort by the Clinton campaign to show the business community's support for the Democratic nominee.

Over the weekend, Clinton picked up another billionaire's boost when Dallas Mavericks owner Mark Cuban endorsed her in Pittsburgh, opining, "Leadership is not yelling and screaming and intimidating," and he praised Clinton as "a true leader." Last week at the Democratic convention, yet another billionaire, former New York City Mayor Michael Bloomberg addressed the delegates and announced his endorsement of Clinton, too, calling Trump "a risky, reckless, and radical choice."

Nebraska is a state that hasn't voted Democratic since 1964. But unlike most of the rest of the states, Nebraska divides its electoral votes (Maine is the other exception). The popular vote winner gets two of the five votes, and the remaining three votes are assigned individually to the winner of each of the three congressional districts. Clinton is campaigning Monday in the most liberal part of the state, Omaha, home of the second congressional district. President Obama won this district narrowly in 2008 against John McCain, but not in 2012, when he ran against Mitt Romney.

Clinton will be highlighting a June study released by Moody's Mark Zandi, which said that Trump's economic proposals would raise unemployment and result in the loss of 3.5 million jobs, while Clintons would create 3.2 million jobs. Zandi, however, supported the Obama stimulus package and has donated to Hillary Clinton's campaign. Two other economists worked on the study with Zandi.
