Why does the mixed electoral system not work in Georgia?

The imbalanced result of the 2016 election alone is sufficient evidence that the Georgian electoral system is flawed. Yet there is another, arguably more important problem with the majoritarian system: those MPs who gain their mandate through such a vote tend to be less active than those who reach parliament via party lists. All too often, directly elected MPs seek a parliamentary mandate in order to ensure that their business interests are protected. It appears that they are repeatedly successful not because of their personal popularity and integrity but because of their ability to control power networks in their districts. Indeed, they often switch parties depending on who is in the government to ensure that their influence is maintained. Thus, the majoritarian vote seems to favour the incumbent party and its preservation of power.
