I'm not sure what to make of this. On the one hand, you have the Kansas referendum results. On the other hand, you have the Michigan referendum consistently polling roughly in line with typical D/R partisanship in the state.
It feels like in MI, the abortion referendum has become more polarized as it's been talked about for months whereas in KS, it was a very quick spike in coverage leading to less time for things to get as polarized.
It does seem like Prop 3 should outrun the Dem ticket by quite a bit, but it's not going to be some 30 point blowout we may expect based on KS.
