TRENTON, N.J. (CBS) — One of those rumored to be willing to take on New Jersey Governor Chris Christie in his re-election bid has filed papers to run in the 2013 Democratic primary.

North Jersey State Senator Barbara Buono is the first to make her candidacy official. She posted a three minute, professionally produced video on YouTube on Tuesday, citing New Jersey’s high unemployment rate, and Christie’s response to it.

“Instead of bipartisan leadership,” Buono says, “Governor Christie’s offered trickle-down economics, policies that have landed New Jersey 47th out of 50 states for economic growth. We need a real plan to create good paying jobs all across our state.”

Newark Mayor Cory Booker is expected to decide on a gubernatorial run by the end of next week. Among those believed to still be thinking about it — a pair of locals — Senate President Steve Sweeney and Assembly Majority Leader Lou Greenwald.
