Like all Americans not of the First Peoples, they have immigrant roots - Ukranian. They have achieved great material success, accumulating one of America's largest fortunes.

JB went to Duke and Northwestern where he apparently succeeded quite well in earning rather than buying a degree in Political Science and a Juris Doctorate. He passed the Illinois Bar, created his own capital investment company and won awards for promoting entrepreneurship and job creation in Chicago.
He "came up" through the Democratic Party and worked to promote Party engagement among under-40 voters.
He poured his own and family money into his campaigns rather than grifting voters and selling goodies to big money donors.
He nominated a woman for his running mate and has given Lite Goob Juliana Stretton active and meaningful roles in his Administration. His Administration has moved strongly to support civil rights of all types and worked hard on public safety, gun control, net neutrality, progressive taxation and raising the state's minimum wage to $15/hr.
If he finishes his current term he'll be the first Democrat to complete two terms as Illinois governor, and he's made no secret of planning to run for a third term.
He's popular and has built a broad and deep web of support both in his own state and among Democrats generally.
He's EVERYTHING [Redacted] hates and fears except female and/or brown.
interestedly,
Bright
