It’s a day of complicated logistics, but I should be back on task for the afternoon.

Here are some midday news/views treats, southern deep fried:

* Legal challenges emerging to the “two-tier” voting systems (a proof-of-citizenship requirement for state and local elections) being planned by AZ and KS.

* TNR’s Alec MacGillis adds his well-informed voice to the mockery of those anachronistically wringing hands over the demise of the Senate As We Knew It.

* Slate’s Dave Weigel looks at the nuclear option from the perspective of long-time progressive filibuster reformers.

* The Atlantic‘s Conor Friedersdorf criticizes the over-blown rhetoric of “nukes” and “humiliation” surrounding filibuster reform.

* At TAP, Gabriel Arana discusses the frustration and fatigue besetting the immigration reform movement.

And in non-political news:

* Winning $16 million Powerball ticket bought in Tamps expires after six months.

As we break for lunch, here, by request, is the late Lou Reed with “The Day John Kennedy Died.”
