I don't think computers are ever going to be good enough to do it. Because any and all issues would have to be TO black and white, yes or no.
BUT, I don't see any reason we couldn't have a website in which BILLS, or ISSUES are put up in full, and voted on. Like forinstance the healthcare reform bill. One side SAYS the country is overwellmingly FOR it. The other side SAYS, OH no the country is overwellmingly AGAINST it. So why can't we have a single place where we can read the bill, have links to research from both points of view, and VOTE as if on the ballot. We may need to add a thumbprint reader to keyboards, to keep it one person one vote, but that would be easy enough. If a vote comes out very close, it needs to go back for revision, but if the vote IS totally one way, thats that. If you just don't want to vote on any issue, don't buy a new keyboard. This could help stop the tacking on of pork barrel add on BS that turns what should be a simple logical bill into 2,000 + pages of BS.
