A pattern has emerged as Republican candidates for Illinois governor: each ticket includes someone from a Chicago collar county.

Wheaton City Council member Evelyn Pacino Sanguinetti will be Republican governor hopeful Bruce Rauner’s running mate, he announced this morning.

The daughter of an immigrant from Ecuador and refugee from Cuba, Sanguinetti is in her first term on the Wheaton council and worked as an assistant attorney general under Republican Jim Ryan…

His pick puts a suburban name on every Republican ticket for governor.

State Sen. Bill Brady of Bloomington chose former Long Grove Mayor Maria Rodriguez as his running mate, and Illinois Treasurer Dan Rutherford chose businessman Steve Kim of Northbrook. Dillard picked state Rep. Jil Tracy of Quincy.

Additionally, the main Republican primary candidates (Rauner, Brady, Rutherford, and Dillard) are all white males who selected a running mate who is not a white male: three women and a man who is “potentially the first Asian American to hold state office.”

So the strategy appears clear: try to win the suburban Republican vote, particularly in the populous Lake County and DuPage County, and appeal to various demographics (Illinois is now 71.5% white, 15.8% Latino, 14.5% black, and 4.6% Asian American). Expect to see the Republican candidates plenty in the Chicago suburbs in the months ahead…
