[pp.int.general] GNU/Linux-powered voting machines in Brazil

[Richard M. Stallman]

If voting machines use software, it should be free software.
But just having free software in voting machines does not make
it possible to trust them.  We need to be concerned that the
manufacturers, or the election authorities, will fiddle with them
to steal the election.

It appears that Bush stole the 2004 election in Ohio that way.
