Perhaps a "case can be made." It is you who chose not to "stick with what the ACLU actually says," but to add that "voter-punched machines are less accurate," and to assume that low income districts are minority districts and that low income districts probably would buy cheaper machines.
As you wrote, "stick with what the ACLU actually says." By doing so you may be able to grasp what they meant rather than having to defend what you hope they meant.
Good debate. Again, I hate the ACLU as much as anyone, but don't think their quote or this article is the best way to attack them (perhaps the RICO act...). Anyway, I guess we can agree to disagree (as fellow freepers). Secret handshake.
