On June 5, the Seventh Circuit upheld a challenge to the Illinois ballot access law for primary candidates in Cook County, Illinois. A Democratic candidate for Sheriff needed signatures of one-half of 1% of the Democratic Party vote in the last election, which in 2018 was 8,236 signatures. Acevedo v Cook County Electoral Board, 18-2979. The plaintiff argued that he could not be required to collect more than 5,000 signatures, because statewide primary candidates in Illinois only need 5,000.

The decision says that the plaintiff failed to introduce any evidence showing that it is a severe burden to collect 8,236 signatures. Illinois does not have registration by party, so any voter was permitted to sign if that voter had not signed the petition of anyone else running in the Republican primary that year, or had not signed for another Democrat running for Sheriff.
Here is the 8-page decision.

The decision is by Judge Amy Coney Barrett, a Trump appointee. It is also signed by Judge Amy J. St. Eve, a Trump appointee; and David Hamilton, an Obama appointee. Thanks to Thomas Jones and Rick Hasen for this news.
