Betting markets now give Democrats a strong edge to take the House, which is bad news for Republicans heading into the midterms.

• Traders put the odds of Democrats winning the House at over 90%, with tens of millions of dollars riding on it.
• Republicans are given less than a 10% chance in the same market.
• The Senate is much closer, with Democrats only slightly ahead at about 60-40.
• Winning the House alone would not give Democrats full control, so the Senate race is the one that decides how much changes.

Outlook: Expect the House odds to stay lopsided while the Senate stays a real contest, and watch the money flowing into these markets as the vote gets closer.
