I wonder how much the original city voted and its racial demographic.
I'd guess it's similar to the IN -7 district, which voted 58% for Kerry.
No, it's much smaller. (I've no idea how democratic or black it is, though.)
In 1960, the city had 476k inhabitants and covered 71k square miles
In 1970, the city had 745k inhabitants and covered 379k square miles - a larger area than today, actually (361k square miles)
IN7 covers 262k square miles.
The city boundaries had expanded several times before, btw:
1910 (earliest data I found) 33k sqm
1920 44k sqm
1930-40 54k sqm
1950 55k sqm
1960 71k sqm
1970 379k sqm
1980 352k sqm. The 1970s were also the only decade ever that Indy's population fell in.
1990 362k sqm
2000 361k sqm
