Several Senate Democrats up in 2012 have already joined the million-dollar club, including Kent Conrad of North Dakota, Bill Nelson of Florida, Dianne Feinstein of California and Sherrod Brown of Ohio, as well as independent Sen. Joe Lieberman of Connecticut, who caucuses with Senate Democrats. Several more are expected to surpass the million-dollar mark when the latest round of campaign finance reports is released Oct. 15.
Lieberman, who had $1.4 million through June 30, said he was unsure whether he would run in 2012 as a Democrat or an independent.
"Or a Republican," Lieberman jokingly added. "I have all sorts of options."
