Straight Party Tickets
The only argument that I can imagine in favor of the straight party option on a ballot is that someone might accidentally vote for the wrong candidate when they mean to vote for candidates from a single party. This is where technology can help us. Since we have already moved to touch-screen voting machines we could change the straight party selection so that the straight party selection would make the candidates from our chosen party stand out but the voter would still be expected to select the individual candidates for their votes to be cast in each race.
