The presidential race may be inducing whiplash, but the House battleground remains relatively stable in the final week. We rate only 40 House races in Lean or Toss Up, and Democrats would need to sweep 35 of them to win control, so Republicans remain overwhelming favorites to hold onto their majority. But there is still plenty of uncertainty about the size of that majority: Democrats could gain anywhere from 5 to 20 seats. CONT.
