Go back to local politics? Why the only direction should be always up? At the end, who cares?
Career politicians with most power who reach the top will always be good primarily at one thing - bullshitting their way to the top in various sociopathic manners that no power structure anywhere is immune to. Those who are inside the circus for 30+ years? Expect them to be rotten to the core while wearing very polished masks, seeing and dealing with the worst and staying on top. Not a place for a nice good hearted well intending folks.
Don't expect some common good to come out of them just because it would be nice or proper thing to do, either its by mistake as a byproduct of some other effort or some pre-election campaign.
