Baltimore County Del. Jon Cardin launched his bid for Maryland attorney general Monday morning with a web video that includes testimonials and recounts legislation Cardin passed in the General Assembly.

"I'm running for attorney general in this rapidly changing world to protect our families, children, our seniors, and I want to make sure that we, as a state, are keeping an eye on the most vulnerable among us," Cardin says in the video.  

Cardin joined the legislature in 2003 and most recently worked on legislation to criminalize cyber-bullying and tighten campaign finance laws, as well as a failed bill that would have further regulated speed cameras.

Cardin, a Democrat, is the first candidate to announce his bid for attorney general. Several other state lawmakers are also considering a bid to succeed Attorney General Douglas F. Gansler, who plans to run for governor but has yet to formally join that race.

In the video, Cardin is lauded by fellow Democrats House Majority Whip Talmadge Branch and U.S. Sen. Ben Cardin, the candidate's uncle.
