Wisconsin Democrat Tammy Baldwin voted yes, and Republican Ron Johnson voted no. Johnson said he favors a level playing field but the bill puts “too much of a burden on online retailers.” He had planned to offer amendments but Majority Leader Harry Reid closed debate.
The bill now goes to the House, where observers say it faces tougher sledding.
State revenue officials say Wisconsin would get an extra $95 million a year, once the compliance mandate is fully implemented. Stores with less than a million dollars a year in online sales would be exempt from the proposed law.
