Politics may be the art of the possible, but sometimes it seems more like the science of expediency. A recent example: the Senate bill which would require online retailers to collect state and local sales tax for purchases they ship to customers.
Yesterday, this legislation survived a procedural vote, and is expected to be approved, perhaps later this week. So, what's this online sales tax all about? How will it work, who will pay what, and who's for and against it?
