The Battle Creek Enquirer profiles a couple area political races.
The 19th state senate district covers Calhoun and most of Jackson counties. Two Republicans, Elizabeth Fulton and Al Cavasin are competing for the Republican nomination to challenge Democrat Mark Schauer. Schauer is a strong incumbent, but this is a Republican district, so it could be a pickup in November. I'm not sure how much the article helps, but here it is.
The 87th state house district covers Barry and most of Ionia counties. Seven Republicans are seeking their party's nomination. This is a safely Republican district, so the primary will determine the November winner. This article profiles six of the candidates, but doesn't do much to distinguish them.
