UPDATE: Michigan election results for the November 2008 general election, if you came here from a search.
The polls have closed, and results are just starting to trickle in at 8:30pm. Here's some places to look for data. (update: it's the next day and the votes are tallied)
The Michigan Secretary of State has 2008 Unofficial Michigan Primary Election Results for all state-wide races, state senators and representatives, and judicial races. They also have links to Michigan primary election results by county connected to almost all of the county clerk sites maintained around the state.
In Washtenaw County, there's a page with unofficial Washtenaw County election results for August 2008, including cumulative results and a breakdown by race. Notable contested races are the Democratic primary Washtenaw Sheriff election, and the 15th District Judge race. The Ann Arbor News has a roundup of results..
The Oakland County non-partisan and proposal ballot results include a proposal for a tax to support the zoo, which passed. The Detroit Free Press has complete 2008 August election results.
All of the 2008 Marquette County August primary results are on one page. (Two friends from high school are both running for judge.) I expect to see voting results at the Marquette Mining Journal, but nothing there as of 9am Weds.
More details as anything is notable.
Several newspapers have coverage with Twitter - the Ann Arbor News has an (ahem) unofficial feed, and mLive does some state-wide coverage. Other newspaper twitters are dead including the Flint Journal and the Detroit Free Press.
