Tuesday is primary election day in Wyoming. Laramie County Clerk Debbye Lathrop says the polls will be open from 7 a.m. until 7 p.m.  She says there have been some changes in polling places since the last election. If you are not sure where your polling place is you can call the Laramie county clerks office at (307) 633-4264 or go to their website,  go to the elections page and click on the polling place search link.  Enter your street number only, then you will be shown all addresses in the county with that number.  Simply click your street name and your voting location will be shown to you. Lathrop reminds voters that if you are registering for the first time, making address change or wanting to change your political party at the polls, you must have a valid picture ID.  Lathrop also says this year there will be no paper ballots only touch screen machines for you to vote on.
