The election rules in Illinois are extremely complicated. Voters will actually vote twice -- first for their preferred GOP candidate, and then for delegates to the GOP convention. Illinois has 69 delegates, but only 54 will be awarded on Tuesday. The remaining 15 -- three of whom are party officials -- will be selected at the state convention in June.
