So much is on the line this election cycle and predictions are plentiful. POLITICO has done an interesting analysis:

POLITICO analyzed every midterm race for the House, Senate and governor to determine who we think will win. We used historical trends, the latest polling data, evaluations of both parties' campaign strategies and extensive reporting in our analysis. Read about it here.

Every race is rated on a scale. Solid seats heavily favor a particular party. The party has a narrow edge in a Lean seat. Likely seats fall somewhere in between while Toss-ups are races we think are too close to call.
