There not being a better play doesn’t mean that play is a good one. It is a bad play, just the least bad one. What it means the system overall is broken and careening ro a crash, since the actually good plays are not politically viable. Mind you not that they wouldn’t be voter viable, but the gatekeepers who get to choose what is put in front of voters viably don’t want them there, that kind of politically non viable.
Always 50/50 because two party system, FPTP and electoral college.
