Bailey was one of a half dozen candidates in the GOP primary that also included Richard Irvin, the mayor of Aurora, Illinois in metropolitan Chicago. Irvin’s campaign was boosted by millions in support from billionaire conservative Ken Griffin, the CEO of Citadel, the multinational hedge fund and financial services behemoth.

But thanks to attacks from the right on his conservative credentials, and a deluge of ads from Pritzker and the Democratic Governors Association blasting him for months, Irvin lost his front-runner status in public opinion polling in recent weeks.

The Democrats meddling to sink Irvin’s campaign scored a massive victory on Saturday, when former President Donald Trump — at a rally in Illinois — endorsed Bailey, whom Democrats view as the weaker general election candidate.

Pritzker, thanks to his incumbency and his massive campaign funding and name recognition advantages, defeated a primary challenge from the left from Beverly Miles, a nurse and U.S. Army veteran from Chicago.
