What was the incentive for Nebraska to start splitting their electoral votes? It looks like it first began in 1996. Was one party or the other more interested in it?
Incidentally, the original proposal in Maine was to divide the state into four electoral districts, which was the normal scheme for states with district election of electors. Feel free to draw a 5-district Nebraska.
For fun, here is said 5 district Nebraska:
NE-01: Obama+10, Clinton+7, D+1
NE-02: McCain+12, Trump+17, R+11
NE-03: Obama+1, Trump+8, R+5
NE-04: McCain+31, Trump+51, R+25
NE-05: McCain+41, Trump+58, R+29
In terms of electoral votes, the downtown Omaha vote would be Likely D, and with trends borderline safe at this point. The Omaha suburbs district would still remain as Safe R, at least in the short and medium term.
The southeast Lincoln district might have been winnable for a Dem at some point in a landslide and was narrowly won by Obama in 08 (and might still be winnable?) but it is a very uphill battle.
The other 2 districts would of course be titanium R.
