Cities are run by Mayors and City Councils. These are non-partisan elected officials.
The "problems" you mention are most often found in large cities. Democrats are frequently the majority in large cities, while Republican strongholds tend to be the more rural areas of the country.
You will also find that homeless folks gravitate to large cities. Social Services, which many homeless folks rely on are more readily available in large cities.
This is nothing new, throughout history, heavily populated (crowded) areas have had more issues, such as crime and homelessness.
This map of the U.S. gives one an idea what parts of the country lean red verses areas that lean blue. This map of Texas a Red state shows how the population is distributed. You will notice the blue areas are the most heavily populated. Oregon is considered a blue state. Notice on this map that the major cities are Democrat dominated, but that area wise most of the state is red or purple.


Thanks for a reply & posting lots of colorful maps,
Only you didn't offer any explanation for why this is allowed to
repeatedly happen the same things over & over again
If the states Governor is democrat why are they Not intervening & speaking out
about the horrendous problems - many soon find a loud enough voice to
slag off Republicans or stand up for Queers / fagggots / & Weirdos etc.
It's like a Huge Elephant in The Room they all Desperately Avoid.
Why do so many Dem run places have such awful problems ??
Potrland and that Antifa lot having their own area - WTF
California completely Fucked - illegals / Shiting in streets / OTT taxes
Philadelphia
Chicago is there a war going on there with the amount of weekly shootings
Just to Name a Few
WTF is Going on -
Why Biden sending Billions of $s to over to Zelensky - why doesn't he concentrate & keep that money & deal with sort America out - not having a Proxy war with Russia via Ukraine.
Sort his one Country out 1st.
He also left Billions of $s of equipment in Afghanistan & what from what I'm hearing [could be wrong ] is paying Isis fighters in Ukraine - If true that's more than Fucking Bizarre.
