The Case For Range Voting: Democratic Primaries
Ian Kerr, November 20, 2016
In a recent post, I mentioned the notion of Range Voting in Democratic Primaries.
For full details on the mechanics of it, see rangevoting.org. The process in brief: it's the same process by which they judge figure skating or gymnastics in the Olympics. Each judge (voter) gives each contestant (candidate) a numeric score (not just the contestant/candidate they like the most); highest average score is the winner.
First, I'll provide an example that starts with real Primary Election results and theorizes how Range Voting might have changed the outcome.
Hypothetical Example - Arizona Democratic Primary 2012
By the time Arizona held its Primary, there were only two active candidates in the race, Hillary Rodham Clinton and Bernie Sanders. The actual vote totals had Clinton winning by 15%:
What the raw vote totals do NOT tell us is the level of affinity for each candidate among voters for whom that candidate was NOT their first preference.
Candidate | Votes | Pct. |
CLINTON | 262,459 | 56.3% |
SANDERS | 192,962 | 41.4% |
OTHERS | 10,600 | 2.3% |
466,021 |
What the raw vote totals do NOT tell us is the level of affinity for each candidate among voters for whom that candidate was NOT their first preference.
Suppose ...
A) these voters could have cast their ballot by Range Voting -- allowing them to rate each candidate on a scale of 0-to-9 (9 best).
B) each vote from the actual Primary (above) were worth the maximum 9 points to the candidate for whom the vote was cast. That would leave the following number of voters the opportunity to further rate each candidate:
Candidate | Additonal Ratings* |
CLINTON | 203,562 |
SANDERS | 273,059 |
OTHERS | 455,421 |
*Total ballots cast minus number of actual votes received.
C) Clinton supporters had a generally more-favorable view of Sanders than Sanders supporters had of Clinton... such that the table below describes the frequency with which each candidate received each possible additional rating:
**there would be no rule against giving two or more candidates the same rating, including the highest rating.
C) Clinton supporters had a generally more-favorable view of Sanders than Sanders supporters had of Clinton... such that the table below describes the frequency with which each candidate received each possible additional rating:
Additional | Candidate | ||
Rating | CLINTON | SANDERS | OTHERS |
9** | 5.0% | 7.0% | 5.0% |
8 | 5.0% | 15.0% | 13.0% |
7 | 5.0% | 15.0% | 13.0% |
6 | 5.0% | 15.0% | 13.0% |
5 | 15.0% | 11.0% | 13.0% |
4 | 15.0% | 11.0% | 13.0% |
3 | 15.0% | 11.0% | 13.0% |
2 | 15.0% | 11.0% | 13.0% |
1 | 10.0% | 2.0% | 2.0% |
0 | 10.0% | 2.0% | 2.0% |
D) THEN the final result would give Sanders the win:
RATING | CLINTON | SANDERS | OTHERS |
9 | 272,637 | 212,076 | 33,371 |
8 | 10,178 | 40,959 | 59,205 |
7 | 10,178 | 40,959 | 59,205 |
6 | 10,178 | 40,959 | 59,205 |
5 | 30,534 | 30,036 | 59,205 |
4 | 30,534 | 30,036 | 59,205 |
3 | 30,534 | 30,036 | 59,205 |
2 | 30,534 | 30,036 | 59,205 |
1 | 20,356 | 5,461 | 9,108 |
0 | 20,356 | 5,461 | 9,108 |
AVERAGE | 6.68 | 6.86 | 5.11 |
Also relevant... the total number of "enthusiastic" supporters (voters who gave each candidate a 7, 8, or 9) and "detractors" (voters who gave each candidate a 1 or 0).
Candidate | Enthusiastic | Detractors |
CLINTON | 292,993 | 40,712 |
SANDERS | 293,994 | 10,922 |
OTHERS | 151,781 | 18,216 |
What does this illustrate?
1) Someone with as much as a 15-point margin in a "check one box" vote might NOT be the most popular candidate in the race. Only Range Voting could illustrate this.
2) The most popular candidate almost always has to be the one with the most "enthusiastic" votes.
3) The candidate with the most "detractors" almost always will NOT win.
#2 & #3 are especially important in a Primary election... because there's a General Election to be won thereafter. The enthusiastic voters are the ones who will knock doors, make phone calls, put up yard signs, give people rides to the polls, talk up the candidate with friends... they're the foot soldiers in a successful ground game. The detractors will entertain the thought of voting for a different candidate in the General Election... and some will actually do so.
Again the breakdowns above are not based on any scientific study of Arizona's Democratic Primary voters... but I don't think it's unrealistic. This example raises the possibility of 40,000+ Clinton detractors having voted in this Primary (more than 1 in 12 Primary votes). Third-party candidates garnered more than 140,000 Arizona votes in the General Election. It's totally possible that 3-in-10 of the 3rd party votes came from Clinton detractors who voted in the Democratic Primary.
