I don’t think you understand how laws work, but that’s no surprise given how stupid you are. If these Dem mayors could implement the gun control necessary to save lives, they would. Gun violence is actually higher per capita in rural counties than in cities.
The major cities with the lowest gun death rates are all in blue states. NYC, SF, SJ, Boston, Seattle, SD, LA, and Long Beach. Each of those cities have per capita gun death rates that are 1/10th to 1/3rd those of your dumb fuck republican states with loose gun laws. It is the pro-gun bs policies that result in so many gun deaths, not the dem mayors who have no control over gun policy.
You can blame the mayor all you want for the crazy republican nutter gun policies that actually cause those deaths all you want. But the reality is that you need to make up such dumb fuck things to say because you don’t have any legit facts to support your point.
