Issued on January 20th, 2021.... Didn't Joe Biden just win the popular vote with 51.3% on... November 3rd, 2020, over two months ago? Why does the US political system wait months to enact the peoples' will? I don't understand this at all.
Is this a serious question? This is what most systems do right? Hold an election and then the newly elected sit at some later point in time. Or are you suggesting the second we know the winner the previous president should be booted out?
I believe, in many parliamentary systems the parliament is dissolved first after which government becomes a caretaker government and cannot enact major new policy changes. After an election is held, new members of parliament are elected and must form a governing coalition that has a majority of the members (sometimes with one party, sometimes with multiple parties) can select a new prime minister and start governing in earnest. Sometimes, they cannot come to an agreement on a governing coalition and they continue without a government for a while until they can. Belgium is infamous for having gone years without a real government that can enact policy due to their failure to establish a majority coalition. This is however very unusual.
Over the past couple years I'm strongly starting to believe that this is a better system of government than the US republican[1] model.
[1] by republican, I mean of a republic, not the GOP
