The party made the announcement Sunday night at an event marking the 100th anniversary of the birth of President Ronald Reagan. The Illinois GOP says the straw poll will be Nov. 5 and measure the support of Republican presidential hopefuls.
The ban on executions goes to Democratic Gov. Pat Quinn, who must sign the legislation for it to become law. During last fall's campaign, Quinn said he supports "capital punishment when applied carefully and fairly," but also backs the 10-year-old moratorium on executions.
The Senate voted 32-25 to approve the ban, with two members voting present.
