2010 Senate Ratings: GOP & Dems Make Gains, It's A Wash

With a whole slew of events and latest polling, here are our current race ratings:

CA-Sen: Toss-up to Lean Dem (favors Dems)
CT-Sen: Lean Dem to Toss-up (favors GOP)
DE-Sen: Lean GOP to Likely Dem (favors Dems)
KY-Sen: Likely GOP to Lean GOP (favors Dems)
NC-Sen: Likely GOP to Safe GOP (favors GOP)
NH-Sen: Lean GOP to Likely GOP (favors GOP)
NY-Sen: Likely Dem to Lean Dem (favors GOP)
WA-Sen: Lean GOP to Toss-up (favors Dems)
WI-Sen: Toss-up to Likely GOP (favors GOP)
WV-Sen: Lean Dem to Toss-up (favors GOP)

Despite the political earthquake of Christine O'Donnell upset and the subsequent strengthening of the Democrat position in Delaware, the GOP makes significant gains in WV and WI. Overall, it's a wash and we're right back to where we were a few weeks ago. There are some minor movements with WA and CA's latest polling showing movement to Dems and a surprise in Kentucky (polling has tightened).

However, the GOP has put new seats into play with DioGuardi's strengthening position in New York. Connecticut is also now a toss-up race.
