I think it's pretty presumptuous to blame Philly's crime issue literally solely on Larry Krasner though? Not sure what the thinking there is.
Also, Vega having the "backing of Police union organizations" is something that... I don't imagine will play well considering organizations like the FOP are corrupt and terrible, and it's widely known in Philly.
I'm absolutely critical of the police, but not so far left as to think that they should be defunded, etc. as some do - but I also don't think any of Vega's prop-police stances help *at all* in this city.
I'm sure it will be closer as some as others have said, but I still imagine Krasner pulls it out.
I regret that "defund the police" has become this ideological spat when what it basically means is that police budgets are overblown, filled with administrative corruption, purposed to buy military-grade equipment they don't need, and really just means that fighting crime would be more effective if large sums were transfered to social programs.
Which brings me to my beef with the OP (and why I agree with you)--we are living through the prelude to an economic catastrophe and given that every study that has ever examined crime and poverty has come to the same gd conclusion every time when are we going to acknowledge that the DA will do nothing to change crime in a city. It's not like criminals are out thinking, "Well now that Krasner is DA I'm going to do more crime."
Not a single shred of evidence suggests that except rightwing (baseless) talking pts, in Philly or in SF or anywhere. It's economics and poverty and if you want to solve crime solve those problems first.
