The only reason an incumbent may have an advantage is because they have already won an election. They have earned the attention. Also plenty of incumbents have been voted out.

Plus you are forcing people to make a decision on the incumbent in the middle of their term in order to allow time for campaigns and a lot could change over that time. You are limiting the time to implement their agenda. You are also forcing the incumbent to have to spend time dealing with the distraction of not just one but two elections during their term.

You are also putting the incumbents party at a disadvantage because they have to wait for the yes no election before they can start to come up with an election strategy while the other party will have a few years head start.

On top of that, you would be setting up a situation where you would have three separate elections to determine who is president.

I think the current primary and general election is enough. I think your proposal is actually kind of silly based on silly presumptions.
