How about you? Should electoral thresholds be reduced or abolished or do you think they should be maintained or even increased?
I'm not for it. Anyway, we don't have it in the US because we have a "first past the post" system, to use the language of wonks, so the concept of the threshold doesn't apply. Some states have ballot-access thresholds, however, and the debates always some threshold allowance. I'm generally against them altogether for the USA.
In societies where there's a parliamentary system, like Germany, their own internal rules might make sense, but I'd have them lower. You have to figure out how to slice the pie. I'm not sure how many seats the Bundestag has, but if it has 500 seats, then make the threshold 1/500 of all votes, or two-tenths of one percent. That way a party gets represented proportionally. Even that would present logistical challenges, though, because getting enough for one seat in one region is different than getting enough for one seat, but having it distributed throughout the land.
