It's vouching by another form, putting the vouching in the hands of the home care officials or administration. However, home care facilities will have a mix of residents, citizens and non-citizens, and I don't know how that's better than having the vouching process that is described in LIB-9, LIB-13 and some others.
If I had to pick between the two, putting it on the administration to provide the list and verify that the list is of only eligible voters, which is how I understand it.... I don't know if that's any better. In fact, it might be worse.
