Wisconsin Senator Russ Feingold was one of only six democrats who voted against keeping a ban on military-style assault weapons Tuesday.
The move reverses Feingold's position on the original ban a decade ago. The ban passed the Senate, but was killed hours later when the Senate defeated the bill it was attached to.
Feingold says he's come to believe that the ban on some semiautomatic weapons is a largely arbitrary and symbolic measure. Feingold did side with the Democrats on another amendment requiring background checks on all buyers at private gun shows. But that also went down with the larger bill.
