Which do you think are likely to flip?
Ballotmedia have a model to describe which legislatures are "battlegrounds", which I feel in an environment like this is rather pessimistic for Dems, with only R-held six chambers seen up for grabs (both in NH, the ME, CO and NY Senates and the MN House) and 10 D-held chambers labelled (the WA House? The DE Senate? The NM House?

They have also identified seven potentially flippable chambers, of which five of them are currently R held.
I'm surprised that the Iowa House isn't mentioned. Due to the non-partisan redistricting, most districts are competitive and Democrats were swept out of a majority in 2010 that was larger than the one Republicans currently have.
I could also see the Michigan House and potentially an Arizona chamber flipping.
