McAuley graduate Elizabeth Anne Walsh appears headed to victory in the race for the O'Brien vacancy. Her margin is less than 6,000 votes in the City, but she has a better than 19,000 vote margin in the suburbs.
Other McAuley graduates have not fared as well. McAuley graduate Elizabeth "Beth" Ryan is running second to Kelly Marie McCarthy in both the City and suburbs for the Coghlan vacancy. An appointed judge, Judge James T. Derico, was the Cook County Democratic Party's slated candidate in that race.
McAuley graduate Jacqueline Marie Griffin ran second to Judge Celestia L. Mays in both the City and suburbs. Mays was the Cook County Democratic Party's slated candidate.
Another McAuley graduate, Jennifer Patricia Callahan, is running a strong second in the race for the countywide Mason vacancy. Slated candidate Chris Stacey has 120,547 votes, City and suburbs, to Callahan's 114,488.
Maura McMahon Zeller, the Cook County Democratic Party's slated candidate for the C. Sheehan vacancy, has a significant lead over Deidre Baumann and former Judge Russell W. Hartigan. An FWIW commenter claimed Zeller is also a McAuley graduate, although I can not confirm this.
Zeller, Walsh, Ryan, and Callahan were all endorsed by the Chicago Federation of Labor in this primary.
