For comic book publisher Bluewater Productions, it’s not superheros that bring in the big bucks, it’s politicians.

According to a piece on Politico, the publisher has sold 130,000 copies of a comic about Michelle Obama. “She competes with Justin Bieber just a little bit,” Darren Davis, the company’s president told Politico about the bestseller.

Comics about other politicians are also popular sellers. Politico has more: “More than 25,000 copies of both Clinton and Palin’s comic books were sold, and Davis and Schultz haven’t looked back since, going on to produce comic books on political figures including Colin Powell, Ronald Reagan, Bill O’Reilly, Caroline Kennedy, Al Franken, Nancy Pelosi, Michelle Obama, Arnold Schwarzenegger and George W. Bush.”

PW Daily reports that Nancy Pelosi, Speaker of the House of Representatives, has signed with Doubleday to publishe her memoir. The deal for North American rights was made by Doubleday president and publisher Stephen Rubin, who acquired the untitled work from a trio of the William Morris Agency‘s top executives: chairman Norman Brokaw; vp and co-head of the agency, Jennifer Rudolph Walsh; and senior vp and president Mel Berger.

The memoir will be published in the summer of 2008 and Pelosi’s collaborator is yet to be determined. It will focus on the Speaker’s remarkable life both personally and professionally. “When Nancy Pelosi, surrounded by her six grandchildren, took the gavel as the first female Speaker of the House in January 2007, it was an historic moment in our nation’s history,” Rubin said. “She stood there as wife, mother, grandmother and political leader; her ascension and remarkable career have put the lie to the notion that those roles are in any way in conflict. How she managed to serve her country without compromising her family is a story both fascinating and inspirational, and Doubleday is proud to be publishing it.”
