Hate to burst your bubble, but if you think the Democrats are on a roll for 2018 because of these two elections you have forgotten how much money they had to pour into them.
I agree I think the Democrats need to help the economy. Working men and even help people to not have to work. Better healthcare might actually work well with this.
As a strong believer in Raelian Geniocracy, a social commandment given by the Elohim to Rael, I suggest only having genius candidates and trying to make it so that those 10% above average IQ decide the election. This sometimes happens to some extent or another anyway. This is known as Geniocracy and I think the Greeks did it if I'm not mistaken, plus in early America there were systems aimed at giving the deserving more of a vote, though sometimes misguided.
