Well, today Bishop said he's going to take his time reviewing the proposed smoking ban before the Senate takes any action.

However, the hold-up doesn't seem to be over the debate whether or not smoking should be banned in the workplace, rather, it seems to be about whether or not there should be exceptions.

At this point, the ban seems inevitable. If it does pass, Michigan will be the 38th state to have some kind of smoking ban in place. That seems like the expected outcome anyway. Even though Republicans are typically more likely to oppose this type of measure than Democrats, the bill had bi-partisan support in congress and as I already mentioned, the discussion by senate Republicans seems to be who, if anyone, should be exempt, not whether or not the ban should be put in place.
