The Republican base is motivated nationally. Communication strategies for Democratic candidates have to modernize to motivate a higher percentage of the base.

Spring, off-year election. No coattails from a Senate or presidential race.

Rural areas in the Upper Midwest are leaning very strongly towards the GOP. This is a critical fact to keep in mind as we approach 2020. Ohio, Minnesota, Michigan, and WI are all affected by this.

Overconfidence. Yes, looking at the qualifications, it should be an easy Democratic win. But IMO, as a whole we as Dems assume too much and don't put enough of the work in to win 50/50 races. Whoever is able to volunteer, work with the county parties, host events, etc. should double up these efforts.

Vote suppression. We all have to know the relevant calendar and restrictions on voter registration and make sure our base knows these details.

In our blue island county (Eau Claire) the vote was 58% for our candidate. This used to be a more purple county, but an extremely active base keeps it leaning blue. Without sustaining and improving on organizing efforts we could backslide.

This is a bellweather for 2020! Time to put the work in!!
