As I recall, Gov. Jay Hammond once opined that an alternative method to the current voting system was that each citizen deserved one vote, positive or negative.  In that system you could chose to vote FOR your choice of candidate, or AGAINST the candidate you liked least.  This would be in lieu of the current two party system where you must vote for the D or R candidate you like least if you don't like either; gamble on a third party candidate (if there is a good one); or worse, not cast a vote at all.

The system lets you vent your frustration on a candidate you seriously don't want while making a meaningful statement on the candidates.  Positive and negative vote tabulation would certainly show a trend.  This would have been a good system for the 2016 election!

I like the subject "ranked-choice" system better than the two party system.
