Illinois is one of 48 states that give all of its electoral votes to the presidential candidate that wins all of the state's electoral votes. Because of widespread discontent over the occasional loser having a bigger popular vote than the winner, various kinds of reform have been offered.
One that appears to be gaining steam, according to this report by the National Council of State Legislatures ("The Electoral College: New Attention to an Old Idea," second item in the link), is a system in which one electoral vote is awarded to the candidate who wins the popular vote in each congressional district, with the two remaining going to the candidate who wins the statewide popular vote. Sounds fairer to me than the winner take all system.
The other reform is the National Popular Vote. Under it, each state pledges to give all of its electoral votes to whichever candidate wins the popular vote nationwide. The pledge takes effect only when states with a majority of the electoral votes sign on to the system, which hasn't yet happened, and which might be losing steam. Eight states and the District of Columbia have enact NPV legislation, but bills have either stalled in other states or have been rescinded.
Illinois doesn't appear to be a player in either proposal.
