Gov. Ige and Lt. Gov. Tsutsui.

Why didn’t they get along?

One reason might have been due to the fact that they ran separately in the race, but not as a team.

Then, why is the system like this?

My take is that establishments and special interests might have wanted in this way; because it might have been easier for them to control our politics and politicians, putting them more under their power.

Just like in the part time schedule in legislature, they might have also purposely wanted our politicians to be more vulnerable for temptations from special interests.

We may need to break and change this system (e.g. by having them run as a team and by changing their term to a full time schedule accordingly with salary increase); so that, our public servants can delve more into serving the general public.
