Actor and musician Andre “3000” Benjamin of OutKast provides the voice for the star character in the new prime-time cartoon series “Class of 3000” (7 p.m., Cartoon Network). He also co-produces the show.

Benjamin’s character is world-famous musician Sunny Bridges, who walks away from his career at the height of his fame to become a humble music teacher at an Atlanta school for performing arts. There, he teaches and inspires a diverse group of kids, helps them find their musical muse and continually gets them out of trouble.

In the first episode made available for review, a precocious hip-hop star and drummer accidentally sells his soul to a record label run by Satan himself. “Class” has an original and often arresting graphic style, the music is memorable and Sunny cuts a slick silhouette. But the kids don’t exactly stand out, the dialogue is uninspired and the stories don’t live up to the show’s look. The cast of “Class” includes the voice of Tom Kenny (“SpongeBob SquarePants”).

¢ With the midterm elections only four days away, CNN will rebroadcast a marathon of its “Broken Government” series, as well as two Lou Dobbs specials. The “America Votes 2006” series runs from 6 p.m. to 2 a.m.

Hourlong prime-time programs include “The Do-Nothing Congress” (7 p.m., CNN), a look at how increased partisanship and the need for constant fundraising has resulted in legislative gridlock. In “Two Left Feet” (8 p.m.), Candy Crowly interviews Democrats about voters’ perception of their party and their problems getting elected and offering a clear alternative message. Jeff Greenfield hosts “Where the Right Went Wrong” (9 p.m., CNN), presenting interviews with conservative writers, activists and candidates who believe that Republicans have abandoned their faith in small government and fiscal responsibility.
