PA Senate Still a Toss-Up

Party-switching Sen. Arlen Specter lost Tuesday's Democratic primary to Cong. Joe Sestak. Specter's Pennsylvania seats is now open for the fall but it remains a Toss-Up in our ratings.

We're also keeping our rating of the Connecticut Senate race as Clear Advantage for the Incumbent Party for now until the dust settles on Attorney General's Richard Blumenthal's (D) past statements about his Vietnam-era service.

While events between now and November will affect the outlook for November, the GOP seems most likely to net 5-7 Senate seats, with a 8-seat gain certainly possible (but still short of the 10-seat gain the GOP would need for control). That means Democrats are likely to retain control of the Senate, but at a dramatically reduced level.

Here are our latest Senate ratings.
