Senator Enzi doesn't understand his own Marketplace Fairness Act

Senator Enzi from Wyoming is the lead sponsor of the Marketplace Fairness Act in the Senate. Yesterday on the Senate floor he said many things about the MFA that were false, but the most head-scratching statement he made was when he said government-mandated software was so easy to use that "all [sellers] have to know is the [customer's] zip code."

Come again?

Anyone who knows anything about sales tax collection knows you cannot find the sales tax rate of a jurisdiction using the zip code.  The reason is that multiple jurisdictions overlap zip codes.  You have to know an exact street address to know which jurisdiction's rate to apply.

The senator who sponsors the Marketplace Fairness Act doesn't understand that sales tax jurisdictions do not map to zip codes?

Say it isn't so.

Watch the startling admission below.
