It's the same motivation behind massive, forced immigration. Political parties that lose voters due to bad policy and bad results need to hack the voter rolls to replace all the voters they keep losing. If crazy people hadn't been deinstitutionalized in the US, elections wouldn't be nearly as close as they have been. Or, more likely, the Democratic platform would be very different than what it is today.
