The Democratic National Convention will take the state's top Democrats to Denver beginning Saturday.
State law requires the governor to be in the state. So, the Garden State will have four gubernatorial switches in the week ahead.
Gov. Jon Corzine will hand over the state to Sen. President Dick Codey on Saturday.
When Codey heads to Denver on Monday, he'll transfer powers to Attorney General Anne Milgram, the fourth in the line of succession. Assembly Speaker Joe Roberts, who is third in line to be governor, is ineligible to serve because he'll also be in Denver.
Milgram will be governor until Codey gets back to New Jersey late Wednesday.
Corzine resumes his role as governor Sunday.
