While no one in Wisconsin will use the notorious punch cards to cast their vote in Tuesday's primary, many will still use paper ballots.
The Legislature banned the use of punch cards in Wisconsin after the 2000 presidential election.
State Elections Board director Kevin Kennedy says 85 percent of all votes in Wisconsin are counted using the optical scan method. Fifteen municipalities still use lever machines and more than 900 use paper ballots.
Kennedy says more rural areas use the paper ballots because of small populations.
He says even though the paper system is time-consuming and prone to human error, the Legislature hasn't pushed for a complete switch to computerized systems because each machine can cost $4,000.
Kennedy says touch-screen technology is the system of choice for the future since it's so easy to use.
