On Monday, by a comfortable 69-27 majority, the U.S. Senate passed a controversial bill that will require online retailers with annual sales of more than $1 million to collect state sales taxes. Said Republican Mike Enzi of Wyoming: "This bill is about fairness. It's about leveling the playing field between the brick-and-mortar and online companies, and it's about collecting a tax that's already due. It's not about raising taxes."
