By my count, the only house races that could truly still go either way are: #AZ01, #AZ06, #CA13, #CA22, #CA41, #CA47, #CO03, #CO08, #NY22, and #OR06.
Democrats need to win 8 of these 10 to keep the house. Not impossible, but highly unlikely.
Treating each of these as an uncorrelated tossup (which is a serious oversimplification), Democrats would have about a 1 in 6 shot. My ballpark is that it's actually somewhere around 1 in 10.
Primary calls:
Dem:
#RIGov Dan McKee (inc)
GOP:
#NHSen Don Bolduc
#NH01 Karoline Leavitt
#NH02 Robert Burns
With that, the primaries of 2022 are complete.
