So you seem to concede we already have a 'ruler' now. To that point, how will the others be any less of a ruler then? I don't subscribe to the theory that we already live under a ruler. But I do believe that simply exchanging one politician for another will do nothing to significantly change anything for the better. In fact, Trump represents our last opportunity to take the presidency back for the citizens. If Trump loses, you can bet the politicians will rig the system to make it virtually impossible for a 'rogue' outsider to get this close again. Trump gave them a scare and they will be on guard to ensure it doesn't happen again.
0bama doesn't govern but he does try to rule. That's a fact. How many times has he lamented about having to 'work with congress'? 0bama failed as a ruler because he's basically a weak, spineless rabble rouser.
Trump, on the other hand, has been 'ruling' his companies his entire life. You don't govern a company, you rule it. That's what he knows and that's what he'll do if elected president.
