Michigan State Legislative Races: Offense or Defense?

Hello there. Since many of the congressional campaigns have raised over $1 million at this point, I thought I would set up an exercise that focuses on state legislative campaigns with heavy up-ballot impacts. As of now, I believe that donations to the Democrats running in these races would be far more effective than federal campaigns due to the law of diminishing returns. Based on my initial searching, I thought that this would be a suitable place to make such a thread.

Below is a list of state senate and state house districts that I feel are competitive and provide the most bang for any bucks spent in these races. The Offense section has Republican incumbents, while the Defense section has Democratic incumbents.

Offense:
Michael Weber, SD-9

Mark Tisdel, HD-55
Ron Robinson, HD-58

Defense:
Kevin Hertel, SD-12

Mai Xiong, HD-13
Denise Mentzer, HD-61
Angela Whitwer, HD-76

Since I probably will not have time to cover all of the above state legislative races, please let me know any districts you are interested in seeing more details in. If I do not have any responses within a day, I will assume that this is not the right place for the exercise, apologize for wasting space, and will delete this post.
