I can't speak for the rest of the state but I was able to walk in, vote, and leave. Voter number 25 in my Green Oak precinct. I voted for Santorum. There was no campaign activity that I saw either, although there was some grumbling overall about the number of robocalls out there.
Besides the presidential primary, we have:
State Rep elections for the old 29th and 51st districts. Good luck to Bob Gray and Joe Graves.
A millage election in the zone covered by Howell area fire authority.
Updated - 1:20. Looks like low turnout in other parts of Livingston County as well. Parents were 89-90 around 12:30 in a heavily GOP precinct in Genoa Township.
