Analysts think Doug Burgum could be named as former President Donald Trump’s running mate, sparking widespread interest in the North Dakota governor’s life, career, background and finances.

The 67-year-old has governed the state since 2016, but before entering politics he was a well-known businessman and led a software company that was acquired by Microsoft for more than $1 billion. Other business interests boosted his bank balance too; he spent millions on his own White House bid last year, briefly trying to run against Trump before dropping his plans and throwing his weight behind the former president.

Now Burgum’s name has been cited by several political commentators compiling lists about who may be chosen as Trump’s for Republican vice presidential candidate and bookmakers have said the odds are firmly in his favor. Being awarded the role would automatically create a favorite for the 2028 Republican nominee for president if Trump were to win and complete his second allowed term.

With just weeks to go until the GOP convention, political news outlet The Hill said Burgum was in the top three “most likely” contenders, along with senators J.D. Vance of Ohio and Marco Rubio of Florida.

Business magazine Forbes estimated last November that Burgum is a worth $100 million “at least.” The magazine said he is worth much more than his financial disclosures would suggest, though, because some of his riches are likely to have been disbursed in trusts for his three grown children.

The governor had relatively humble beginnings, working in his family’s grain elevator business through school and college at North Dakota State University, then becoming a chimney sweep before entering an MBA program at Stanford University.

Following the $1.1 billion sale of Great Plains Software in 2001 to the tech giant, Burgum became a senior vice president at Microsoft and was awarded more than 1.7 million Microsoft shares, which then were worth roughly $100 million, according to Forbes. He later left the firm and over the coming decades sold stock regularly as well as undergoing a costly divorce from his first wife, meaning that today the Microsoft stock is just a tiny fraction of his overall portfolio and is worth up to a $1 million.

But Burgum branched out into a string of other business ventures. He has also worked in real estate development and venture capital.

Some analysts have said money is a key factor playing to Burgum’s advantage because he appears to have been modeled in Trump’s own image. He has “two things Trump wants: a fat wallet and thick hair,” Bloomberg columnist and former political reporter Patricia Lopez joked in an opinion piece on Sunday.

While the Associated Press said: “Trump likes rich people. North Dakota’s two-term governor is most definitely rich.” Burgum and his wife, Kathryn, who are said to be extremely friendly with Trump and his team, would bring “money and rich friends to the table.”

Burgum has remained tight-lipped about the VP situation, but he has been a regular face on TV screens as he campaigns for Trump.

Trump told reporters in Philadelphia this weekend that he had chosen who he wanted to join him on the Republican ticket for November’s election but added that he had not yet revealed his choice to anyone.

Newsweek has reached out to Burgum via the governor’s office seeking further information and comment.
