As long as current trends continue, Marion County (as well as Lake, St. Joseph, LaPorte, Delaware, Monroe, and Perry) will vote Democrat for the forseeable future.
I agree on the rest, but I don't think it's certain at all that St. Joseph, Delaware, and Perry will all vote Democrat for the forseeable future. St. Joseph and Delaware both snapped considerably back toward the Republicans in 2012 and will likely vote for the GOP if the GOP ever wins a presidential election. Both were closer than the national margin. Perry has been discussed extensively already, but simply because it's held out from the Republican trends of the surrounding counties thus far doesn't necessarily mean it will forever.
