Analysing the electoral results

Day 829, 07:29 Published in Netherlands Netherlands by Miro86

Yesterday we saw another exciting elections at the UNL. The main question is of course who won and who lost. The big winners are of course I&W who now have 47% of all congress seats, which is a lot. Congratulation guys. LP are up one seat and that was to be expected given their recent growth. However let's have a quick look at the results themselves.

First of all, less people voted this time, which is not a positive development. In some regions (East) congressmen were elected on the base of a single vote, which is a bit sad.

Another thing that we can look at is activity, where the number of votes per member function as a proxy. We can clearly see that in this area, LP is well ahead of its competition. I&W is second, LSD and GLD are respectively 3rd and 4th and the least active party is the Belgian Party.

Another interesting area is the ability of the different parties to vote strategicually. As a measure here i use the ratio of votes per seat attained for each of the parties. Surprisingly, despite their large numbers, I&W were best at coordinating and averaged at 5.26 votes per seat, second were GLD, closely followed by the LP. LSD performed abysmally, showing an inability to coordinate its members.
Combining the measures of activity and strategic voting we get the ratio of members per seat, where I&W and LP perform the best. LSD and BP have the worst ratios.

Finally we can look at the disproportionality of the system. Here I compare the obtained results under the current system, with a hypothetical case in where the most proportionate system is used. As proxy of this most proportionate system i use the following: Single district, M=40, PR-LR using the Hare quota. Unfortunately i do not have the computational resources to recalculate the results using PR-HA with the Sainte-Lague formula which is arguably more propostionate. Given the large size of M, there should not be too much of a difference. What we can see is that GLD profit the most from the system by getting an extra seat or 25% more. In absolute numbers however I&W gains 3 seats, which is quite an amount.

The table should speak for itself. Green is good, red is bad. The first 4 columns were obtained from eAnalytics. The next 3 columns contain the ratios: votes per seat; members per seat and votes per member. The 8th column contains the hypothetical results using a single district PR-LR (Hare) system. The last column is the percentage gain in seats in comparisson to the most proportionate scenario.
