UPDATE: Some readers were asking good questions about how, exactly, a ballot can be challenged. Here's what the Racine City Clerk's office said:
1. Poll workers are not allowed to ask for ID.
2. If you go to the polls, pretend to be someone else and know their address, they have to give you a ballot.
3. But, if a voter is suspicious, they can challenge the ballot. At that point, the voter needs to prove their identity.
4. If you go to vote, and someone has already voted under your name, the poll workers call in the state to investigate.
5. If fraud is discovered, the case is sent to the District Attorney's office for possible charges.
One point to remember: You need some sort of identification to register to vote. People who register before the election needed a driver's license number or state ID number. If they don't have either, they could use the last four digits of their Social Security number.
On the day of the polls, you can register with a utility bill or other piece of official mail to prove your address.
In summary, it is possible for someone to vote as someone else without presenting an ID. But doing so puts the person at risk for criminal charges, and even if someone did it 50 times on election days (a huge number considering the long lines, time driving between polls, risk of getting caught, etc.), it would barely sway an election where millions of ballots are cast.
Also, registering to vote requires you to prove your address and puts you at risk for criminal charges.
It would take a massive conspiracy - thousands of people voting multiple times - to sway a presidential election in Wisconsin. Try as some may, there is simply no evidence of that occurring in recent elections.
I voted Saturday at City Hall. When I stepped up to receive my ballot, the poll worker asked to see my driver's license. I handed it over, but also told her she couldn't ask for ID to give people a ballot. She mumbled it was about "being safe."
Afterward, I asked my wife (we went together) if she was asked for ID. She wasn't.
That's how the system is supposed to work. Once you're registered, you do not have to provide identification at the polls. Asking a registered voter for ID creates an additional obstacle to voting that the state specifically eliminated to increase voter turnout.
A lot of people worry this will lead to fraud. But in reality, there are low levels of voter fraud in Wisconsin. Aside from a handful of felons who vote, there are no cases of outright voter fraud in the state.
Some people will claim there are cases of voter registration fraud, which is true. But this amounts to someone sending in a falsified request for a ballot, not an actual vote being cast in an election.
As for the ID, I didn't make a scene with the city employee on Saturday. But this should be corrected. Poll workers should not be asking registered voters for identification.
If you don't like it, start by voting Nov. 4 in favor of candidates who want to require a photo ID at the polls.
