Early voting got easier across the suburbs this week, as county clerks opened dozens of additional locations to cast ballots ahead of the June 28 primary election.

In suburban Cook County, Clerk Karen Yarbrough opened 50 additional early voting sites, including at village halls in Arlington Heights, Barrington Hills, Elk Grove Village, Hoffman Estates, Palatine and Streamwood. Most will be open daily through June 27.
