Toomey wins; GOP has now netted 6 in Senate

From the NBC political team
NBC News projects that former GOP Rep. Pat Toomey is the winner of the Pennsylvania Senate race.

Toomey, the former head of anti-spending group Club for Growth, defeated Rep. Joe Sestak in the close contest.

Sestak overcame incumbent (and Republican-turned-Democrat) Sen. Arlen Specter in the state's May Democratic primary.

Toomey's victory means that Republicans have now netted six Senate seats.
