Politics are local in the same way states rights are brought up when a state wants to fight federal funding.

How Mayor Bowser of DC runs the metro is local
How Mayor Turner of Houston declares Houston a sanctuary city is national
The illusion of local politics vs national politics is how it's 2017 and we still have sun down towns in the United States.

We want our local politics to be local issues, stop lights, general crime, law enforcement policies. But since the days of Reagan, when the country shifted to union busting and wide spread migration based on industries and tax breaks we haven't had local politics.
