The rightward view of american policing is basically they're functioning as intended but are not powerful enough to achieve their desired effect and must be reinforced to succeed.
The leftward view is that they're functioning as intended, the violence and fear they cause is success, and so the entire thing must be dismantled.
The "centrist" view is I think something like the goal of policing is good & correct but the system is malfunctioning and must be adjusted. Neither side will agree with that: the right doesn't agree that it's malfunctioning (except so far is that it's held back from achieving its goal) and the left doesn't agree that its goal is just.
There's no neutrality or inherent virtue in a centrist position: it's a side like any other and you don't get credit just for inhabiting it. That doesn't make anyone calling you a nazi or communist justified in doing so or correct in their assessment. But it does indicate that neither considers your stance a compromise or allied position in relation to their own.
I don't know what it would be like to select political goals based on their likelihood in the face of such incredible violence and injustice as we create. I'm grateful I can't lathe my soul in such a way. Seems chill though.
The Overton window can move surprisingly quickly, and policies which you consider extremist now won't be in a decade.
Not sure we got the least worst.
Individual results will still rightly depend on voters. You can blunt the attraction of extremism, but hearts and minds need shifting before voters will take a fundamentally different approach.
I'd support that if it were coupled with multiple-choice position forms that were required to be filled out by each candidate, covering core issues and options. That is, no free response, not-an-answer answers.
But yes, I totally agree with your proposal. I can even see it helping with cutting through all the boilerplate verbiage candidates are having to use to pay respects to various things, and return some focus on actual policies.
Which is a shame, because "knowing what you're voting for" seems like a critical component of democracy, and campaign ads are useless (and expensive).
