I don't know how good Larry's crystal ball prediction ever is, but there it is.
HOUSE: 239 at least Leans Democratic, 196 at least Leans Republican (D+24)
SENATE: 53 at least Leans Democratic, 47 at least Leans Republican (D+6)
GOVERNORS: 28 at least Leans Democratic, 22 at least Leans Republican (D+4)
The D Senate seat flips are: Maine, Ohio, North Carolina, Kansas, Texas, Alaska. No R flips.
