Yeah, I tried to calculate the CD results the best that I could and came up with this:
But, there were a number of precincts (maybe 50 statewide?) that were split between CDs, so I allocated them to whichever district had more of the precinct. Works really well for about 2/3 of them, but some were split pretty evenly.
Why don't you just do a pro-rata allocation based on the relative population of a precinct in each CD? Heck if you use the DRA to see if a split precinct seems to be variegated somehow demographically - you know nice houses in parts of it, and apartments in the other.
