On June 10, 2015, Gov. John Kasich signed a bill delaying Ohio’s 2016 presidential primary by a week. The primary will now be held on March 15, 2016. As Cleveland.com reports, the bill ensures "Republicans will be able to award all their delegates for the national convention in Cleveland to a single candidate." Ohio joins three other states in holding their primary election on March 15, 2016 — Florida, Illinois and Missouri.
