Republicans no longer have a realistic path to picking up the 17 seats they need for a majority. In fact, if the 25 races in our Toss Up column were to break evenly, Democrats would pick up five to six seats. Right now, the most likely outcome is a Democratic net gain of between five  and ten seats, with anything from no net change to a Democratic gain of 15 seats possible.

I can't think of another election cycle when a party picked up 41 seats in an election and then picked up another 5 to 10 in the next.  Certainly not in the modern era.

With the House majority safe and the Presidency as good as it can get the focus is on the Senate and there things don't look so rosy.  Cunningham, the Democratic challenger in North Carolina is in a sexting scandal and Hegar the Texas candidate just proudly announced she didn't vote for Obama in 2008 or 2012.  So two winnable seats are now very questionable (NC) and probably out of reach (Tx)

So it now looks like the Republicans will keep the Senate
