There are often tough problems with either no easy solution or no pratical solution at all in some cases. But good guys like FDR kept trying and experimenting until something good happened. I see Pete as sort of in the FDR mold. rather than the fake Clinton model. Much time will tell.
On the other hand people like Trump simply are out to exploite problems and end up making them much worse. Thus if Mayor Pete should be lucky enough to replace the orange abomination, the nation and the world will be way better off for it.
