Border security is very much a partisan issue, with the far-right being very much opposed to freedom of movement.
I mean... If you vote to let violent criminals out of jail in the hopes violent crime will go down, something is missing up there. This has been my universal experience with democrat voters. It is what drove me away from the party. They'll trust 'experts' ridiculous advice over their own common sense. Most of them are extremely partisan, and will quickly label any independent candidate as a Republican, which is enough reason to not vote for them.
Either way, democrats have been in charge of cities for years in this country and it simply hasn't turned out well.
I often align with democrats on fiscal policy, but the voting bases inability to use common sense reasoning and their overuse of the cliche of everything being 'complicated' has driven me away
