The smaller precinct finished first: Bush 3, Carson 8, Cruz 24, Rubio 25, Trump 16. Not only did Rubio win here, but the Fiorina supporter had switched, and I'd guess to Rubio. This was also the precinct with four early departures, who at least two if not all four were for Trump.
The larger precinct was done a couple minutes later: Bush 1, Carson 20, Christie 5, Cruz 55, Fiorina 2, Huckabee 2, Kasich 3, Paul 2, Rubio 31, Trump 30. The church group for Cruz carried the day in this precinct, but the turnout for Rubio was enough to top Trump here, too.
This might better be placed in the Political Demographics board, but the precinct patter was interesting.
Linn County Republican CaucusWhat is different about the northern part of the county vs. the southern part.
Cruz strongest in the north, Rubio in the southeast, and Trump to the south bleeding into the southern parts of Cedar Rapids and Marion. It is interesting that your two precincts were on the boundary line and split accordingly. Rubio also had wins in the northeastern and southeastern parts of Marion and western Cedar Rapids. Are these leafier areas?
I'd assume any influence from the University of Iowa would be more regional - that people in Linn County drive south for football and basketball games, but there would not be that much distinction from persons living in particular areas of the county.
You will see similar patterns in other areas - see the box of Tama-Benton-Iowa-Poweschiek, which form a continuous Trump precinct block in the center (east-west).
Incidentally, my Aunt and Uncle lived in Marion in the 1960s.
