Indiana Democrat Rep. Joe Donnelly is thinking of running for Senate or governor. The Indiana state legislature may help him along with that decision:

A redistricting plan proposed by Republicans who control the Indiana Legislature would shift several GOP-leaning areas into the northern Indiana congressional district narrowly won last year by Democrat Joe Donnelly.
The congressional map puts all of Elkhart County and most of Kosciusko (Koss-ee-OSS’-koh) County into Donnelly’s current district and removes part of Democratic-leaning LaPorte County and all of Kokomo…
The map also shifts what has been a swing district won last year by Republican Todd Young further north, giving it all of heavily GOP Johnson County just south of Indianapolis.

Republican Jackie Walorski already announced she wants a rematch. The margin of victory in that House race was 1.3 percent, the 12th closest House race in the country.
