New Jersey Gov. Jon Corzine and his GOP challenger, Chris Christie, have more time to choose their running mates than previously thought. A bill sitting on Corzine’s desk spells out details about the newly created lieutenant governor position. Secretary of State spokeswoman Susan Evans says the governor has 45 days to sign it. Until he does, no deadline is in place for picking lieutenant governor candidates. The proposed law requires gubernatorial candidates to pick running mates within 30 days after the results of the primary are certified. The results must be certified by Aug. 10. Independent Chris Daggett is also running for governor. The 2009 governor’s race will be the first New Jersey contest to include a lieutenant governor candidate. AP.
