Democrat J.B. Pritzker has already contributed $76.5 million toward his campaign and Gov. Bruce Rauner has given $50 million to his own.

They are on track to surpass the record-high $280 million spent on California’s 2010 governor’s race.
Some critics say its an example of how the current campaign finance system discourages diversity among candidates and limits ballot access for hopefuls not affiliated with wealthy special interest groups.
