There are several types of democracy. Ours is representative democracy. We elect people who in turn, vote on our behalf. In the 18th century, it simply wasn't possible to vote fast enough (collectively), to do it ourselves. Fast forward 240 years and we have the technology to vote directly, in real time. Perhaps in place of legislators or perhaps with proposition systems popular in some states - occasionally bypassing lawmakers, who continue to do the day to day stuff. Would it be practical? Can 30 million people find time enough in their day to keep track of issues large and small. Or limited to just 2-3 dozen propositions every year or two, would the powers that be control such a process, nullifying the results or worse? Would you want the opportunity (and responsibility) of voting in national elections, not for people, but for actual laws/outcomes?
