Each primary election I get numerous phone calls from voters who are disturbed by the Illinois requirement that you declare your party affiliation at the polling place on election day in order to be able to participate in the party primaries. I’ll try here to give some explanation for why this is done.
Before examining the closed primary system, it is good to identify the terms, which often confuse people. A closed primary is one that is closed to people who are not members of the party. In Illinois, you become a member of the party on election day by OPENLY declaring your membership in the party that day. An open primary is one where you don’t have to declare your affiliation.
The closed primary is set up to prevent what is called party raiding. That is the practice of members of one party crossing over and influencing the primary of the opposite party. Those “raiders” could either vote for a candidate who holds views very similar to their own party or, more cynically, for a candidate that they believe would be easiest to beat.
In years where the nomination is far from certain (like 2008) this is not a major issue. But in years where one party’s nominee is certain (for example the Republicans in 2004) it could be an issue.
The Republican and Democratic Party Delegate selection rules each recognize this concern and thus require that a person’s party affiliation be publicly declared.
The Republican Party rules state: (page 8 )
(2) Only persons eligible to vote who are deemed as a matter of public record to be Republicans pursuant to state law or, if voters are not enrolled by party, by Republican party rules of a state, shall participate in any primary election held for the purpose of electing delegates or alternate delegates to the national convention or in any Republican caucus, mass meeting, or mass convention held for the purpose of selecting delegates to the county, district, or state conventions, and only such legal and qualified voters shall be elected as delegates to county, district, and state conventions;
The Democratic Party rules state:
1. Democratic voters shall be those persons who publicly declare their Party preference and have that preference publicly recorded.
So while the Illinois legislature could alter the law to make Illinois an open primary state, it is likely that neither party would recognize the results of that election.
The “closedness” of primaries across the country varies. In Illinois, there is no declaration of party at the time of voter registration. Instead, you publicly declare your affiliation on the day you vote in the primary election, regardless of how you have voted in the past. In fact, you could even declare for one party, get in the polling booth, change your mind after you see the ballot, return the ballot to the judges, and get a new ballot of another party!
Illinois law changed this past year to become more forgiving of party switching. In previous elections, if you had signed a petition for a candidate of one political party for a primary election, you were unable to vote in the same primary election for a different political party. Now you can vote in any primary, regardless of what petitions you may have signed in the past.
Compare that to the State of Florida. There you have to register your party affiliation with the County Election Office at least four weeks prior to the primary. So for Florida voters, that would need to have been done prior to the first votes being cast in Iowa.
Because so many voters in Champaign County, and throughout the state, routinely switch their party affiliation from one primary to another, no one should skip voting because they feel that they are being “labeled” when they declare their affiliation on February 5.
This presidential primary season has been the most exciting in my lifetime. I expect record turnout, even with the closed primary rule.
