You’re only able to choose two options, how is that democracy? I thought democracy was about being able to choose anyone you think is suitable to be a leader, not one of two pre-selected people. At that point, it’s not much different to a one-party system, just with two people rather than only one person.
If this is about the US, notice that they used to have intra-party elections as a strong cultural requirement before going into the main election. They only stopped requiring that very recently.
Primary elections never stopped being a thing
