I've always found it interesting how machine politics tends to be very big in minority districts like NY-14 and IL-03, even when the machine's politicians usually (though not always) are white.
Anybody know why this is?
Districts often changed around the machines (sometimes around the specific incumbents). Ed Burke was elected as Alderman of Chicago's 14th Ward when it was mostly an Irish Catholic area and has simply stayed in power as the neighborhoods changed. The strategies to maintaining power aren't much different, though it does create some vulnerabilities that weren't present before; Burke's brother lost his (heavily Latino) State House seat this year to a 26-year-old CPS counselor and soccer coach, Aarón Ortíz, who successfully painted Burke as oit of touch with the majority of the district's residents. Ocasio-Cortez is attempting to exploit the same opening.
