A primary challenge strengthens the successful candidate in the general. Our democracy is deeply flawed, but it always has been. It’s not worse than in the past when only a tiny fraction of the population was allowed to vote. This is the first time in history that we’re seeing serious national discussion of ranked voting, and some states and localities have implemented it.

Approval voting is actually worse than first past the post, in my opinion. We need ranked choice, IRV or STV as appropriate.
