Why Haven't ES&S Voting Machines Been Outlawed? (regarding South Carolina, plus other states)

Here's a great article regarding the ES&S voting machines and the Alvin Greene issue:

A small excerpt from the end of the article:

Politicians now realize that they had best please the Corporate Masters or the elections will be thrown to the other side.

Doesn't matter if the polls reveal that the populace didn't vote for that person.

The Corporate Owned Media will have a story that explains why the last minute switch over. "George Bush was a known quantity." "Kerry looked exhausted and Un Presidential at his last five campaign stops." Etc.

They run those for a few days, and those who say that the election was stolen are told, "Hey if that was the case, why doesn't the media mention it?"

Last fall, ES&S quietly purchased Diebold, giving them 80% of market for electronic voting machings. And it's not just the un-auditable vote-counting; they now also own polling place check-in software (electronic pollbooks), voter registration software and vote-by-mail authentication software.

This link has very scary information, all with appropriate citations, regarding what could easily be a mass-manipulation of our elections.

They've already been caught registering voters who thought they were just signing petitions. Getting total registered voter numbers higher gives them more room to fudge numbers.

When you buy a pack of gum, you get a receipt. Why is there no receipt/audit trail on our votes? I can only think of one reason.
