From Team Sabato:
All nine ratings changes this week benefit Republicans, further evidence of the many advantages they face across the country at this time. The Crystal Ball moves five Democratic seats from a “safe” rating onto our list of competitive races: KY-6 (Ben Chandler), MA-10 (Bill Delahunt), OH-13 (Betty Sutton), SC-5 (John Spratt), and VA-9 (Rick Boucher). In addition, two already competitive races for Democrats look even worse than before — IA-3 (Leonard Boswell) and IN-8 (OPEN, Brad Ellsworth) — and two Republican incumbents have improved their reelection prospects — AL-3 (Mike Rogers) and CA-44 (Ken Calvert).
