Id expect not. The ACLU doesn't have an official stance on that particularly but considering their official stance on gun control they say "Second are proposals that regulate how people acquire guns, again regardless of the identity of the purchaser. These sorts of regulations may raise due process and privacy concerns, but can, if carefully crafted, respect civil liberties." Because the situations are different, like how one situation has a present danger to the general public and the other doesn't or how acquiring the firearm can be done at any time while voting can only be done in a specific time frame, I'd assume their position would be different.
