(CNN) House forecast: Democrats will win 225 seats (and the House majority) while Republicans will win just 210 seats. Senate forecast: Republicans will hold 52 seats (and maintain control of the Senate) next Congress while Democrats will hold just 48. Perhaps, there's no way to understand that better than to look at the following Senate races: North Dakota, Tennessee, Texas and the Mississippi special election. In the Democrats' best case scenario, they need to win every other close race and then one of these four. The problem is that the forecast looks bad for Democrats in all four of these.
