Johnson County has 57 precincts that will open on Tuesday, Election Day, but there are a few things voters should know in general before heading to the polls.
If you still have an absentee ballot, you can no longer mail them out today, but if you live in Johnson County, you can bring them down to Johnson County Auditor's office to be counted.
Do not take them to your polling place or they won't be counted. Yesterday staff at the Johnson County Auditor’s Office counted thousands of absentee ballots.
By 9:30 a.m. on Monday, the office had seen over 20 percent of their registered voters come out for early voting.
If you're wondering about if you're allowed to take a "selfie" as you vote, Travis Weipert, the Johnson County Auditor says the answer is "yes" as long as you aren't trying to persuade someone to vote a certain way.
"The law was changed to allow them however if you're causing a disturbance, they can be considered electioneering so just if you want to take that photo take it real quick in the booth and you know don't be obnoxious about who you voted for or anything like that," says Weipert.
The Johnson County Auditor's office says if you're caught electioneering, you can be fined and even go to jail.
Campaign signs should also be 300 feet away from polling sites unless your home happens to be within 300 feet.
When it comes to wearing something political to the polls like a shirt or a button, you can wear them as long as you get in, vote, and get out and you are not trying to persuade someone to vote for a certain party--that is also considered electioneering.
Travis Weipert the Johnson County Auditor also wants to remind people and especially students, you cannot write political messages in chalk outside the voting sites because that is considered electioneering.
Exit polling is allowed in Iowa, The person conducting the exit poll needs to make sure that person has already voted and they are not interfering if someone coming into vote or committing electioneering, trying to persuade a person to vote for a political party.
Remember you're not required to show ID to vote this year but if you do not have your ID then you will have to sign an oath when you go to your polling site.
Polls will be open from 7 a.m. until 9 p.m. for the midterm election across Iowa.
