secure enough for consumerism, not good enough for voting?!

In the past year or so we have seen various attempts to online voting just to see them scrapped because they are not secure enough. Pentagon Drops Plan To Test Internet Voting is the latest report on such initiative stating that "The Pentagon (news - web sites) has decided to drop a $22 million pilot plan to test Internet voting for 100,000 American military personnel and civilians living overseas after lingering security concerns, officials said yesterday."

How is it that we can't trust security because voting would be done over the Internet, when the same Internet is used for millions of dollars in daily transactions between consumers and companies and business-to-business? The same Internet is secure enough for commerce and can be trusted with billions of dollars. Yet, it is not secure enough for voting?

Something is wrong … perhaps the following explains it (from the same article): "The American pullback is in direct contrast to Europe, where governments are pursuing online voting in an attempt to increase participation. The United Kingdom, France, Sweden, Switzerland, Spain, Italy, the Netherlands and Belgium have been testing Internet ballots."
