It kind of seems ridiculous that we have to choose one person to make decisions on a plethora of issues.
To make it simple, if there are two candidates, and two issues, and I agree with one candidate's stance on one issue, and the other candidate's stance on the other issue, who should I choose?
With today's technology, there's no reason we should have to support an entire set of beliefs just to support the one or two issues we care about. We could just vote on each issue individually on the net.
The reason to not have everyone vote on an issue is to prevent mob rule. That is, if there were 50.1% socialists out there, we'd socialize everything because they'd win the vote.
That's why we have representatives. People have posited we have more of a parliament, however, where basically Trump, Clinton, Johnson and the Green Lady would all have the Executive position. In my mind that's what Congress is though...
