Former Rep. Pat Toomey (R-Pa.) raised $3.1 million in the second quarter and now has $4.65 million cash on hand, according to his campaign.

Toomey outpaced his Democratic Senate rival by more than $1 million.

Rep. Joe Sestak (D-Pa.) did not widely release his second quarter numbers. The campaign instead told reporters that he raised $2 million and has close to $2 million banked.

Sestak has spent the past two months refilling his campaign coffers after a bruising primary battle with Sen. Arlen Specter (D-Pa.).

Fundraising has been a priority. An e-mail from his campaign Tuesday invited supporters to a fundraiser at The Fluor Townhouse near the Capitol in Washington, D.C.

“At this time, we are asking you to please make a maximum contribution as Congressman Toomey has already started advertising and we need the resources to get our message out on our ideological differences,” Sestak wrote in the e-mail.

Toomey recently released five new TV ads, while Sestak has stayed off television since the end of the primary.
