It's a contributing factor, but not something to solve. It arises from our multi-layered forms of government, where states are very strong and hold a lot of power to themselves. Some states have ballot initiatives. Some don't. Some states allow for ranked-choice voting for certain offices. Some don't. Some states (like California) love direct democracy and having lots of elected offices that are normally appointees in other places. This is why it's states--not the federal government--that run elections; each state has a different political system that sets the requirements for elections.
