Tom Fitzgerald at the Inquirer has a nice story on Pat Toomey's efforts to woo moderates, despite his hard-right background at the Club for Growth:

Now, Republican Sen. Susan Collins of Maine - lampooned as "Comrade of the Month" by the Club in 2009 for her pro-stimulus vote - is coming to Philadelphia to raise money for the staunchly conservative Toomey, a sign that his campaign's effort to court moderates is paying dividends.

Collins will headline a $1,000-a-plate luncheon for Toomey's Pennsylvania Senate campaign Aug. 2 at the Union League.

"Pat Toomey gets the fact that he needs to work with a lot of folks, that there doesn't need to be unanimity on all issues in the party," said Washington lobbyist David Urban, an influential GOP moderate and a host of the event.

Urban was Sen. Arlen Specter's chief of staff from 1997 to 2002, when the outgoing Pennsylvania senator was still a Republican. He stayed loyal when Specter became a Democrat last year, and he returned to the GOP fold after Specter lost the May 18 primary to Rep. Joe Sestak.

Urban is helping to connect Toomey with moderate Republicans in the capital and from the Specter camp. He calls Toomey "more of a fiscal conservative than a social conservative."
