Sen. Barbara Buono officially kicks off her campaign for New Jersey governor with a rally in New Brunswick on Saturday.
The Metuchen lawmaker is the Democrats' presumptive nominee to challenge Gov. Chis Christie in November.
The 59-year-old progressive says Christie hasn't done enough for the middle-class and working poor. She says property taxes and unemployment remain too high.
Christie says he's stabilized property tax increases by forcing municipalities to keep their budgets under a cap he enacted with Democrats' help.
