"We are pleased to say that two pieces of our ICE Out package, which take a clear stand against the appalling actions of the U.S. Immigration and Customs Enforcement Agency (ICE), were passed...in a strong show of support by the Common Council."

race is such a β€œhandy” variable. it saturates demographic measurement in us and predecessor colonies. 1783, revolutionaries set a metric for allocating requisitions to pay for the army and war. After the Declaration…before the Constitution. Slaves worth 3/5th of free persons. Actionable.

β€œalgorithmic” decision making has a long β€˜history’ in the history of data and statistics. Alain Desrosieres, The Politics of Large Numbers [Eng. translation], Harvard, 1998, esp. the concept of β€œmaking things that hold” – can be actionable.

Milwaukee, WI: Now…”What do we do about ICE? 3rd District Town Hall... THIS EVENING - Monday, February 2 - meeting REMINDER from Alderman Alex Brower.” Overflow crowd, line to get in snaked around the block, watching on Facebook if not in the room. Looks like there’s a lot of interest. Tks Alex!

Fellows’ Corner: Rogelio SΓ‘enz, 2023 Ernest W. Burgess Fellow – AAPSS

Estimates report for July 2025, first half year of Trump II. Expect more decline from historic immigration patterns, given intensification of anti-immigrant policies.

Four takeaways from the new Census population estimates Immigration declined dramatically. Census estimates now align with other government estimates. The 2026 Current Population Survey population base will be adjusted downward.

On the heels of Lawler’s ICE backpedal op ed, he releases a bill that radically limits counting of immigrants for apportionment, contrary to 14A lawler.house.gov/uploadedfile...

In other words, as well, putting a citizenship question on the 2030 census. Very problematic after the 2020 controversy.

Not Enough. Cong wrote the 15th Amend., ratified in 1870, much simpler:

β€œThe right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitudeβ€œ

Apportionment! The 13th Amend, nullified the 3/5ths Comp. Without addressing the β€œright to vote,” Cong [and Frederick Douglass] recognized that former slave states would end up with more Reps in the House than they had before 1861. The language of Section 2 was the first stab at that problem....

Folks arguing about numbers, how many states [add DC and Puerto Rico maybe], what it takes to pass a bill in the Senate, [50+1 or 60]. Why only 2 senators no matter how β€œbig” the state is - framers worried about that too....

....which was a tried and true technique in the past. Ex: In 1889-90, Cong admitted ND, SD, WY, ID, WA, MT. 12 senators, 7 reps. Total pop for the 6 states - ~same size as city of Chicago at the time. Worked for Republicans!

....Cong. could β€œadd” them to the House, growing the body from 425 to 430 or 431 members. Or Cong. could reapportion the whole House, keeping the body at 425 members and taking away seats from other states.
