Glad tidings for CA elders, but expected.
I would guess they have similar arrangements in Fla and most states.
The trouble is probably with folks who need help and either don't know it's available, or don't think they need it.
In Fla (at the risk of provoking the bull. note: I am trying not to reopen the 2000 Fla controversy, which is dead and gone for me.) there was a definite inexplicably (considering Pat's unpopularity there, and his lack of campaigning) large number of Buchannon votes. Buchannon himself admitted it.
This implies that a lot of people had trouble voting. You like to characterize these people as idiots who should not vote. I like to characterize them as retirees who need voting to be as simple as we can make it.
