hmmm maybe, as long as it's president run system not prime minister run system, and not one party system. tho there are issues with two party system during emergency, which is why i also believe that when we become a galactic empire, we will go back to feudal system as it's faster than democracy when it comes to responding to emergencies
tho planetary democracy is still viable, like there will be sectors, each sector will have regions, each region will have a head similar to countries having a head, and each sector will have a head like a president of the sector, until this point everything is based on election, but then the head of a planet will be a lord by birth or by promotion, like a knight or barron or something else. then a head of a star system will be another lord, then head of a galaxy will be a king and then head of multiple galaxy will be an empire
